Mike your work is fantastic, especially your painting. Is there any chance of writing a "How to paint" all items, ie fiberglass, aluminium in a clear step by step guide for this numpty and perhaps others? Being in the UK the use of Halford's paint and primers makes it easier to obtain rather than the items posted by Halo who's work is also exceptional.

Brynogwy,

Everything you need to know about rattle can spray painting....

RATTLE CAN" BLING! ...everything is here! from DoTheTon

Mike probably uses these same techniques, I'm sure.  Very good prep work, warm the paint, shake the can really really well and keep it shaken periodically,  even motion, constant distance from the object, many light coats, let it cure just right.  It's an acquired skill that needs lots of practice.

Very much the same Rob but I will do a "how to" thread and expand on some of the techniques using some of the images I have from over the years.

Yes, I believe that they do, at least at the bigger stores. I don't know how good they are in terms of covering the range or their prices. I find these people are competitive on price and very quick to despatch:

http://www.extremeautoaccessories.co.uk/products.php?section=5074

It's a bit off-putting that BmW don't appear in their lists but use the search on BMW and the paint code, it will pop up.


Just taken delivery of a pair of K1100RS wheels. I wasn't in any tearing rush to find a 3.5 x 17 front and 4.5 x 18 rear but these were cheap, I made a cheeky offer and it was accepted.

Will I Never Learn? - Page 2 K1100LT%20%28127%29-L

I couldn't resist giving the front one a quick clean to see what the state of the paint is like under all the grime. I quite like the colour, it goes quite well with the pine green (sort of 60's era Lotus colours).

Unfortunately it's pretty bad:

Will I Never Learn? - Page 2 K1100LT%20%28128%29-L

Well for me it is anyway. Shame. A good clean, even a fine rubbing down, followed by a clear coat would have been nice.

For a moment or two I did consider getting them powder coated the same yellow as the K1. That way I'd have wheels that could be swapped between the two bikes but even though it wouldn't look bad with the green I don't think that it would work with the silver transmission.

The rubber isn't bad, Pirelli Diablo Strada with a few thousand left on both.

Thanks again Mike, as a metal worker of some experience I too winced at the massive scratch!

If you aren't already you are rapidly becoming best resto/most fastidious on here, well done.

In my defence (such as it is, I do agree that I'm a bit fussy), they are like that all over and it's just as easy to re-spray them.

I've been a bit side-tracked this week getting bits ready to put up for sale on ebay. 

However, I have addressed the cock-up with the headlamp cowl paint. It meant flatting all the new lacquer back again and dealing with the minor damage caused by the drop. Rubbed down and local skim with stopper (knifing putty):

Will I Never Learn? - Page 2 K1100LT%20%28126%29-L

Once the stopper is flatted-back I mocked-up the headlamp and horn mounting. Usually the horn is of the single tone type on the unfaired bikes. I want to retain the decent twin set-up. They do fit but I'll trim a corner off the trumpet just to ensure there's decent clearance (obviously the horns and headlamp haven't been tidied up yet Wink  ):

Will I Never Learn? - Page 2 K1100LT%20%28130%29-L

So the cowl was given another colour coat and clear coat before cutting back and final polish:

Will I Never Learn? - Page 2 K1100LT%20%28132%29-L

I've opened the Motometer and cleaned all the usual suspects in the way of contacts, tested all the bulbs and removed the ABS one.

Will I Never Learn? - Page 2 K1100LT%20%28133%29-L

Next job, attack the dull outer case. Like the indicator housings, cutting paste does the trick followed by a polish:

Will I Never Learn? - Page 2 K1100LT%20%28134%29-L

As for the mounting, I checked the photos of the rebuild of my old K75C (some years back now) and noticed that the counter-weight is not utilised when the Motometer mounts directly onto the plastic headlamp carrier. 

Will I Never Learn? - Page 2 DSCF2665-L

So I found some large flat washers and shorter (stainless) Allen screws:

Will I Never Learn? - Page 2 K1100LT%20%28135%29-L

Then I couldn't resist checking that it all fits together:

Will I Never Learn? - Page 2 K1100LT%20%28136%29-L

Will I Never Learn? - Page 2 K1100LT%20%28137%29-L

Will I Never Learn? - Page 2 K1100LT%20%28138%29-L

I'm waiting for the clips that hold the black cover in place, a new adjuster bush and headlamp rubber boot but those little parts aside, that's another group of parts that can be bagged and put on the shelf ready for final re-assembly.

Cheers Blakey. I've always thought that that version suits the naked K-Bikes best. It was offered in the UK as a customer option way back when. It sort of ties-in the bulky Motometer better than the naked headlamp version.

Cracking on with the grubby stuff I turned my attention to the exhaust. I really didn't intend to go this far but as I'm not going to get this bike on the road as soon as I'd hoped, I might as well set about doing it all now.

I've been dreading this bit. Along with the main stand, the exhaust headers always seem to be ignored by most owners when it comes to cleaning their bikes. It doesn't help that the K1100LT and RS have the headers hidden behind the fairing (out of sight, out of mind I suppose) where they don't get even an occasional squirt from a hose.

Will I Never Learn? - Page 2 K1100LT%20%28143%29-L

Most studs came out with the nuts (lots of heat applied) leaving two plus one that sheared. On the one that sheared the nut was coming off but the stud had partly corroded away and it was too much for what was left.

The second and third headers were stuck fast too:

Will I Never Learn? - Page 2 K1100LT%20%28143%29-L

They gave in to a thump with a soft-faced mallet and then it was a case of fishing out the old crush-gaskets:

Will I Never Learn? - Page 2 K1100LT%20%28146%29-L

The paperwork that came with the bike shows an invoice for "exhaust welding" and sure enough there's evidence of this at the junction of the header pipes into the expansion chamber. This is going to be a challenge to polish up:

Will I Never Learn? - Page 2 K1100LT%20%28144%29-L

Will I Never Learn? - Page 2 K1100LT%20%28145%29-L

A bit grubby under there:

Will I Never Learn? - Page 2 K1100LT%20%28143%29-L

The oil seems to be coming from the timing chain cover. It as well as the sump cover has the non-original blue sealant you can see in the above image. I know from experience how tricky it can be to seal the timing chain cover fully. I once tried to replicate the factory seal with a thin smear of sealant. It began weeping almost straight away. I've since learned that a liberal dollop of Three-Bond is the answer, then trim off the excess later with a knife blade once it has cured.

I've had a quick scrape and brush to get rid of the worst of the clagg and to reduce the opportunity for it to smoke or even catch alight when I hit the studs with more heat (my gas has run out so it will have to wait a day or so). The sheared stud (circled):

Will I Never Learn? - Page 2 K1100LT%20%28147%29-L

has done what sheared studs always seem to do and snapped in such a way that I can't get an extractor on to it. It's also too short to put two nuts on so I'll get it good and hot then try some pipe grips. I don't want to remove the head unless I really have to.

Broken stud

I had the same problem with mine. Seeing that the thread for the stud is counter sunk by about 2-3mm I took a couple of mm off the rim of the stud hole with a little rotary cutter giving me an extra 2mm of stud protruding allowing me to get the stud extractor on. So with a good dollop of heat and a couple of hail mary's out it came

I never ceases to amaze me how some people can neglect a bike so. At some point in its life an owner must have decided it wasn't worth the effort. What mileage has it done?  Will look forward to your instalment on the stand as my recently acquired K75 sits low on its. John

Postie, My problem is that the stud extractor fouls on the oil gallery near it. There's plenty enough to get a grip on just no room to do so with my extractor.


John, I'm the sixteenth owner! This bike has been loved at some stage (lots of stainless fasteners) but not for a while. The mileage is just over 50K and documented. I think rather that it's where it was used last (in Scotland) and as a winter hack. The bike travelled south to Lincolnshire (probably still covered in road salt from the Scottish winter) to the next owner in May of this year. His intention was to also use it as winter bike and as he had no need to use it straight away, it then sat in a damp shed until last month when he decided to get it ready for use and discovered the seized rear brake. He then offered it for parts or repair.

So, getting ready to remove the gearbox, I took a close look at the clutch pushrod rubber boot now that things are a bit cleaner. It was as black as a very black thing when I stripped the swingarm out. The usual suspects are the gearbox output shaft seal or more often the pushrod boot.

It covers the pushrod thrust bearing and spring, is held by a hose clamp and the clutch actuating arm:

Will I Never Learn? - Page 2 K1100LT%20%28149%29-L

Sure enough, the boot is split:

Will I Never Learn? - Page 2 K1100LT%20%28148%29-L

Who knows how long it's been like that but a little oil goes a long way and as the output seal is okay the muck was probably all from lost gearbox oil and road dirt.

Off with the injector rail (taking the injectors with it):

Will I Never Learn? - Page 2 K1100LT%20%28151%29-L

Will I Never Learn? - Page 2 K1100LT%20%28160%29-L

Then the airbox and throttle bodies:

Will I Never Learn? - Page 2 K1100LT%20%28159%29-L

The lower half of the airbox wasn't actually fixed to the engine. Anyone know if that's how it should be with this model?

Will I Never Learn? - Page 2 K1100LT%20%28162%29-L

There doesn't seem to be any good reason to separate the airbox & inlet tubes, the clamps are all tight and the seal looks okay. I probably will though, if for no other reason than to fit some stainless clamps that can be tightened if needs be.

Will I Never Learn? - Page 2 K1100LT%20%28161%29-L

Before I removed the TB's I spotted that the pipe from the airbox to the balance tube behind the throttle assemblies was not connected. This is a 16v specific arrangement and I believe that it's to equalise air pressure between the TB's above the idle speed.

Will I Never Learn? - Page 2 K1100LT%20%28156%29-L

Will I Never Learn? - Page 2 K1100LT%20%28157%29-L

Now just looking at the brass by-pass screws (BBS), they are all over the place (I haven't removed them yet but when I do I'll count the turns 'till they come out), the TPS is at the extreme of it's adjustment and the broken TB adjustment screws all points to someone struggling to get the TB's to balance properly. Anyone know if the disconnected balance pipe is the likely culprit?

It may also help to explain why I'm the 16th owner!

Anyway, I reconnected it and began cleaning the 20 years worth of dirt and grime away:

Will I Never Learn? - Page 2 K1100LT%20%28166%29-L

I've re-crimped the connectors but I may find a "rat's tail" connector and replace the crimped clips with hose clips.

Bit of a scrubbing:

Will I Never Learn? - Page 2 K1100LT%20%28168%29-L

Including opening the throttles to clean the butterflies:

Will I Never Learn? - Page 2 K1100LT%20%28165%29-L

The injector bodies have been cleaned. The O-rings are pretty good but they'll be replaced anyway. I may send the injectors off for a proper cleaning.

Will I Never Learn? - Page 2 K1100LT%20%28167%29-L

The engine will be cleaned once I've dropped it out of the frame:

Will I Never Learn? - Page 2 K1100LT%20%28152%29-L

The spaghetti monster will be given a good clean while it's out. The redundant ABS multi-connector had been covered in a rubber glove (presumably to prevent water ingress) and taped to the frame. I'd like to chop it off but am concerned that doing so might cause problems so unless anyone knows for certain that removing it and sealing the end will be okay, I'll find something better than the latex glove and tape it somewhere better.

Will I Never Learn? - Page 2 K1100LT%20%28155%29-XL

I'm going to leave it like this for a while:

Will I Never Learn? - Page 2 K1100LT%20%28164%29-L

Will I Never Learn? - Page 2 K1100LT%20%28163%29-L

I'll get the bits that have come off sorted before I remove the stands and the gearbox and I can keep soaking the forward engine mountings ready for the attempt at undoing them.

The inlet rubbers/injector tubes can stay put for now. They look good but they can be a source of bad running if they are perished or cracked. A close inspection will follow once the block has had a clean.

I can smell the oil, I can smell the petrol, I can smell the cleaning fluid, I can hear the hum of the fan heater in the back ground. I'm sat in my computer chair with clean hands, this is my virtual rebuild! Keep it up Mike, this is the best read on the Forum for me. John

that balance tube is not really for balancing ...I believe it gives a more constant suck of the vacume to the oil recovery system through the airbox and crankcase breather ...as the takeoffs are above the butterflies ....so the vacume wouldn't be very high at all till  (wider than closed throttle )  the port sizes wouldn't be enough to allow any considerable flow  through a balancing process at revs .

you may have been running lean on a more than a few cylinders though but I guess the motronic might compensate a little for that ....if it was the later type fitted with the ox sensor ...but all over the place is more likely

 I believe that all the bases of the air boxes are fitted with top washers and insulators on the fixing bolts

leaving them off might add to the characteristic  fracturing of the inlet tubes to the throttle bodies  , which seems apparent an all the 16 valve series

doing good mike ....we love to see the process ..and the way you do it

The lower part of the airbox is not fastened as on as K100 but has 2-3 rubber feet which it sits on and is clipped to the top section

The rubber feet are the same grommets as used on the K75 and 8v K100 but without the bolt passage open. The corresponding receiving threads in the block are all there but look as though nothing has ever been screwed into them.

I agree that as the airbox can't go anywhere once everything is assembled, it may be that it's to allow the air intake tubes to flex. It's obviously a different set-up to the plenum chamber arrangement of the earlier machines. Just never having gone as far as removing the airbox base on a 16v bike before I was initially wondering if this was a Spandau Friday afternoon bike. Very Happy

I think that bike has seen a number of Friday afternoons and not at the factory. I reckon they just jumped on it Friday afternoon and rode it till it didn't move then sold it.

This morning I've made a start on the spaghetti monster. Ordinarily I'd just check and clean the loom, plus all the connectors would get a squirt of contact cleaner but the removal of the ABS has left redundant wires and plugs. In addition, there are some LT-specific bits that won't be utilised, the front section is longer than needed too so I'll be modifying things a little to suit.

I began by pulling off the latex glove from the ABS-Brain multi-connector and stripping off the old self-amalgamating binding:

Will I Never Learn? - Page 2 K1100LT%20%28172%29-L

My plan is to leave the unused sections but re-route them forward and under the tank. This means that the wires to the gear position switch, the fuel tank electrics, speedo sensor etc that are bound to the ABS cable need to be separated so that they can remain in the correct place (under the right-hand side panel):

Will I Never Learn? - Page 2 K1100LT%20%28171%29-L

Then it was time to remove the rest of the self-amalgamating tape. A horrible job. The stuff is either still sticky or turns to dust so you end up with a sticky mess. Good old Wurth brake cleaner and elbow grease cleans the exosed wires:

Will I Never Learn? - Page 2 K1100LT%20%28173%29-X2

As the old binding came off, I cleaned the wires and wherever possible I bunched the redundant items into one sub-loom (the bit on the left of this photo):

Will I Never Learn? - Page 2 K1100LT%20%28174%29-X2

The various sub-strands of the loom were then just given a whip of insulating tape to hold them together for now. Once I've sorted the front section of the main loom and the separate EFI loom, the whole thing will be re-bound with new self-amalgamating tape. Before doing that however, I'll lay the loom and relay box back into the frame to check it will lay cleanly in place.

Now a question for the electrickery gurus.

Having binned the LT screen etc, I'm left with a fair number of bulky plugs up at the pointy-end plus the relays.

Will I Never Learn? - Page 2 K1100LT%20%28179%29-L

Of all you can see (above), there's only the horns, turn signals, headlamp and parking lamp that need power. All the rest will have to be found a home. Unfortunately there's not enough wire to let me double the unused stuff back under the tank, so it will have to be found a home within the limited space inside the headlamp cowl.

I'm concerned that the unused and therefore exposed plugs will just be a source of gremlins once moisture gets in (and it will because the cowl isn't weather tight).

Should I chop the unused stuff off and seal the ends of the wires somehow?

Or should I leave them and try and seal the exposed, open side of the connectors?

If there is enough room in the headlamp shell for the connectors, I'd leave them on and stuff them in.  I don't believe that the connectors will introduce gremlins if they are left open-ended because all the contacts are sufficiently separated.  The advantages of this approach is simplicity and the ability to use the connectors for their purpose later.

If you cut off the connectors, then what will you use to seal the ends.  Heatshrink tubing will eventually fall off unless you use the special glue-ready type. You'd have to probably dip the ends in one of those coatings used for tool handles.  The advantage to this is that the loose wires will take up much less room.

I must admit Robert that one of the reasons for not heavily modifying things is that it could one day be put back as an LT. 

My instinct is to leave the connectors on, perhaps fill the exposed end with a sealer that can be removed one day, re-locate the horns from my original plan to mount them inside the cowl and find an alternative position.

how about getting the as mentioned glue lined heat shrink

in a really big size (suitable for each connector ) ....the double wall variety has a really good shrink rate ...far better than the mono plastic type (which cracks over time anyhow ) and stays rubbery flexible .

what I suggest is to make a sock for each of the connectors
that is make a tube over the connector  a inch or so longer than needed .
you can shrink the heat shrink at the wires end so it should just about crimp up the cables . at the other  or open end shrink the first centimetre of the heat shrink  then using some pliers just clamp the heat shrink  whilst still warm ....this creates a great seal with the glue lining

have used this technique when jointing cables in the field ...in very exposed conditions ....it lasts for many years and doesn't leak at all ....but has to be the right heat shrink stuff to work properly . 

just a thought

Gave the alternator a quick whizz with a wire brush. The only point being to remove the furry crap and to be certain that the face that seats in the bellhousing is free from the usual fur and will sit flush when it goes back in:

Will I Never Learn? - Page 2 K1100LT%20%28183%29-L

Will I Never Learn? - Page 2 K1100LT%20%28195%29-L

The cush-drive rubbers have worn a bit and are just starting to crack so they'll be replaced:

Will I Never Learn? - Page 2 K1100LT%20%28185%29-L

The starter has also been given a quick clean on the outside:

Will I Never Learn? - Page 2 K1100LT%20%28184%29-L

Before opening it for a clean and to check the carbon brushes:

Will I Never Learn? - Page 2 K1100LT%20%28186%29-L

Watch you don't lose this washer on the armature:

Will I Never Learn? - Page 2 K1100LT%20%28190%29-L

If you draw the armature out from the splined end there's a likelihood that the magnets will pull the washer off and you'll have to fish it out.

The body was given a flush with brake cleaner:

Will I Never Learn? - Page 2 K1100LT%20%28188%29-L

As was the base cap:

Will I Never Learn? - Page 2 K1100LT%20%28189%29-L

The commutator cuts were cleaned with a cocktail stick:

Will I Never Learn? - Page 2 K1100LT%20%28187%29-L

Then as the brushes were good, he bearing was repacked with grease and it was re-assembled. The outer casing will get a clear coat to slow the inevitable re-growth of fur.

Next job is off with this:

Will I Never Learn? - Page 2 K1100LT%20%28191%29-L

I will carefully store the cobweb for re-installation.

Will I Never Learn? - Page 2 K1100LT%20%28192%29-L

The LT models have four spacers between the sub-frame and the gearbox to accommodate the taller profile tyres:

Will I Never Learn? - Page 2 K1100LT%20%28194%29-L

It's not as bad as some I've tackled:

Will I Never Learn? - Page 2 K1100LT%20%28193%29-XL

The fixing bolts are longer too. M10x50 for the LT whereas all the other 16 valve bikes use M10x40. As I'll be fitting RS wheels and low profile radial rubber, the spacers will be left off when it goes back together.

The bolts are pretty shabby, even after cleaning so three new ones won't break the bank - only three as the fourth is longer to accommodate the silencer support bracket.

Did something about the soldered repair to the heated grip switch:

Will I Never Learn? - Page 2 K1100LT%20%28176%29-L

I added a few inches of cable and soldered then sealed the joints with heat-shrink (before a sleeve is slipped over):

Will I Never Learn? - Page 2 K1100LT%20%28196%29-L

Been binding the loom with self-amalgamating tape this morning. The bike has two aux-sockets, one on the coil cover and one originally on the handlebar crash pad. I've always though that the best place for one would be in the tail unit where phone & iPod etc could be recharged. So I've re-routed and extended the wires from the front one which will be fitted into the tail unit later:

Will I Never Learn? - Page 2 K1100LT%20%28198%29-L

The now redundant ABS connections look a bit odd under the tape but it keeps them out of harm's way and that whole section of the loom will be under the tank now instead of under the seat:

Will I Never Learn? - Page 2 K1100LT%20%28199%29-L

I've still got to bind the front section of the loom but I'm awaiting some large diameter, glue lined heat-shrink to seal the unused plugs before I do that.

Apart from that, the gearbox screws are all loose ready to remove the 'box:

Will I Never Learn? - Page 2 K1100LT%20%28202%29-XL

and the forward engine mounts have responded to soaking in de-icer, they too are free and ready to allow the engine to be lowered out:

Will I Never Learn? - Page 2 K1100LT%20%28200%29-L

Will I Never Learn? - Page 2 K1100LT%20%28201%29-L

The heat-shrink arrived so the unused bits of the loom having been bundled together and wrapped in self-amalgamating tape then sealed:

Will I Never Learn? - Page 2 K1100LT%20%28203%29-L

Will I Never Learn? - Page 2 K1100LT%20%28206%29-L

So the spaghetti monster can be boxed ready for the re-assembly stage:

Will I Never Learn? - Page 2 K1100LT%20%28204%29-XL

Gearbox off (and these photos are for the perverts who love seeing dirty pictures Wink ):

Will I Never Learn? - Page 2 K1100LT%20%28208%29-L

Either a seal has gone or someone has been overly enthusiastically lubing the splines:

Will I Never Learn? - Page 2 K1100LT%20%28209%29-L

It could be the input shaft seal on the gearbox. It'll take a bit of cleaning:

Will I Never Learn? - Page 2 K1100LT%20%28210%29-L

A start made (I use paraffin followed by Wurth brake cleaner):

Will I Never Learn? - Page 2 K1100LT%20%28211%29-L

Well I know what I'll be doing for a while.

These are odd looking engine mounts.  Does the splined shape have something to do with the uniqueness of the LT?  My engine mounting bolts are normal socket head screws.

John, someone put me on to it more years ago than I care to remember. Basically the old boy said that it's the viscosity and the rapid evaporation that does the job. Anything that is thin enough to flow into the joint and then evaporate quickly will help break the seal between parts.

Buy something like "shock & unlock" (I have a can here that someone gave me), squirt it onto a nut and bolt and a) feel the temperature drop as the stuff evaporates, b) smell it. Then try the same with de-icer and you'll notice the same features.

De-icer is a damned sight cheaper, especially if you buy it in Spring when the winter stocks are sold off. You can afford to really dose the parts.

For soaking, I use paraffin.

Getting back down to work on the gearbox once the worst of the oil and muck is removed I started to chip and scrape away the flaking powder-coat:

Will I Never Learn? - Page 2 K1100LT%20%28212%29-L

Will I Never Learn? - Page 2 K1100LT%20%28213%29-L

Then removed the battery tray/footrest sub-frame mounting bobbins. These are much larger on the 1100 models than the K75/K100/K1 versions presumably because they have to take a lot more weight. They also have a large washer beneath them and part of the cast 'web' on the top of the gearbox has been removed to clear them. That and the Paralever lugs are the differences between the gearbox casings.

Beginning to feather the edges of the solid powder-coat:

Will I Never Learn? - Page 2 K1100LT%20%28214%29-L

The clutch actuating arm is seized to the pin but it rotates smoothly so I'm not going to bother fighting to remove it. 

Also, you can see how badly the aluminium has been eaten away under the cracked powder-coat on the stand mounts (how I hate powder-coat):

Will I Never Learn? - Page 2 K1100LT%20%28219%29-L

The paper gasket under the Gear Position Indicator has been letting crap through:

Will I Never Learn? - Page 2 K1100LT%20%28218%29-L

First time I've used enamel primer. I decided to give it a try after giving the case a coat of enamel bonding spray:

Will I Never Learn? - Page 2 K1100LT%20%28221%29-L

Will I Never Learn? - Page 2 K1100LT%20%28222%29-L

Then a couple of coats of silver enamel:

Will I Never Learn? - Page 2 K1100LT%20%28230%29-L

Followed by a coat of clear enamel lacquer.

I like to stick to my own, sort of methodical, approach by cleaning all the fittings and mountings so that they can be re-attached to avoid losing them or using them for the wrong thing later when I've forgotten where they go. Bits cleaned:

Will I Never Learn? - Page 2 K1100LT%20%28229%29-L

The swing-arm, adjustable pivot was showing some signs of galling. A little work with a fine, v-shaped file removed the few burrs:

Will I Never Learn? - Page 2 K1100LT%20%28223%29-L

If you've ever struggled to remove the bobbins that BMW use in various applications, you'll know why I slathered them in anti-seize paste before re-assembly:

Will I Never Learn? - Page 2 K1100LT%20%28225%29-L

All threads cleaned with a tap and plenty of alumslip on the screws etc:

Will I Never Learn? - Page 2 K1100LT%20%28226%29-L

Will I Never Learn? - Page 2 K1100LT%20%28227%29-XL

Meanwhile, the old tyres have been removed from the replacement RS rims:

Will I Never Learn? - Page 2 K1100LT%20%28220%29-L

And I've begun the laborious rubbing down (still not as bad as doing the black Y-spoke wheels of the K75S):

Will I Never Learn? - Page 2 K1100LT%20%28216%29-L

I'm trying to work out how this gouge can have got onto a spoke of the front wheel.

Local corner shop. Literally. Being a port, there's quite a demand for stainless from the sailing fraternity. H2 & H4 is cheap as chips, go into the shop with a dozen or so fixings for replicating with stainless and they'll do a cash price of a few quid. Usually under a fiver.

For things that are specific such as axle end cap screw and washer or drain/filler plugs I use Shaw Stainless (well known in most BMW circles and available via ebay).

Just an observation...no negative comment.  I notice that you don't mask off machined surfaces before painting, such as between the paralever lugs or where the fixed swingarm pivot bolt up.  I masked all machined surfaces and plugged all threaded and non-threaded holes before I sprayed my K1100 transmission.  Do you clean up the machined surfaces afterwards?  You say in the text that you chase threaded holes with a tap afterwards.

No I don't bother. The reason that some surfaces are machined is that powder-coat is much thicker than paint and it will split unlike paint which will just abrade.

The fixed Paralever hole was wiped with oil before painting, then it just wipes off leaving a quick swipe with fine grit paper to remove anything that may impede the pivot.

As for the Paralever lugs, the only thing that should be in contact there is the centre of the metalastic bush (the same goes for the Paralever bar at the final drive end). The Paralever bar shouldn't be in contact with anything.

With respect to the battery tray bobbins, when I replaced mine earlier this year, I had to use a chisel and hammer to remove the old ones despite being well dosed with coppaslip when previously assembled. (Quite a few years ago!). The threads were free but the corrosion was between the steel base of the bobbins and the alloy gearbox casting.
So, this time, I made some polythene washers to interface between the bobbins and gearbox casting. Hopefully they will be removable the next time they need replacing.......10, 15 years time?

Paul, it should do the trick. The 1100 ones have a large metal washer between them and the casing. It made removing them much easier than I anticipated (I still covered them with Aluslip (as in the photo) just to be sure.

This is the low point in these jobs, endless rubbing, scraping, brushing etc. It's tedious and mind-numbing with very little to show for all the effort.

The wheels, once the dirt is removed, need more work than first appeared. I began by removing the accumulated rubber and lubricant from the rims:

Will I Never Learn? - Page 2 K1100LT%20%28233%29-XL

Will I Never Learn? - Page 2 K1100LT%20%28237%29-L

Will I Never Learn? - Page 2 K1100LT%20%28235%29-XL

Then there's nothing for it but hours (literally) of rubbing down by hand. I used 80 grit paper dry to begin with. This really coarse grit cuts through the paint without too much effort. You have to be careful not to use too much pressure or it will leave deep cuts inn something as soft as aluminium.

The rear wheel has the classic signs of someone having tried to get it out past the ABS sensor ring on the disc (and a nice deep graze):

Will I Never Learn? - Page 2 K1100LT%20%28241%29-L

To save the skin on my fingertips and to make it easier to get into the nooks, I square the ends of an ice-lolly stick (always worth keeping some in the garage as they have many uses), wrap the paper around it and this lets you get into the corners etc:

Will I Never Learn? - Page 2 K1100LT%20%28238%29-L

When the paper loses its effect just slide the paper to the other end of the stick:

Will I Never Learn? - Page 2 K1100LT%20%28239%29-L

Here's another tip, begin with the most difficult areas. That way when you're tired and pissed-off rubbing down, by the time you've got to the easier bits it's not such a grind:

Will I Never Learn? - Page 2 K1100LT%20%28240%29-L

The pitting where the paint has chipped becomes more visible with the rubbing down:

Will I Never Learn? - Page 2 K1100LT%20%28242%29-L

Eventually the first rubbing down is done:

Will I Never Learn? - Page 2 K1100LT%20%28234%29-XL

Then its more rubbing down, this time with 400 grit paper used wet (add a little soap to the water and the paper will be less prone to clogging).

Once all the surfaces have been dried and wiped clean (tissue paper and thinners), the first primer coat can go on. I started by getting the primer into the awkward places and allowing it to dry before doing the rest:

Will I Never Learn? - Page 2 K1100LT%20%28246%29-L

A light first coat followed:

Will I Never Learn? - Page 2 K1100LT%20%28245%29-L

Then some hours later a second heavier primer coat. This was then flatted with 1200 grit paper dry. I prefer to use it dry as primer is porous.

Then the first light colour coat can go on once the surface has been cleaned of any dust etc. The same method, start in the recesses, let that dry and then do the whole thing:

Will I Never Learn? - Page 2 K1100LT%20%28247%29-L

Once the first colour coat is cured, rubbed down again (this time wet), dried off I can see some of the pitting is still visible:

Will I Never Learn? - Page 2 K1100LT%20%28260%29-L

Will I Never Learn? - Page 2 K1100LT%20%28262%29-L

Any blemishes are much easier to spot once the colour coat is on and they can be addressed with a combination of more rubbing down and stopper.

Then another colour coat (thin) as a guide coat to show up imperfections. That's the current position; both wheels are currently sitting with the imperfections filled. Once it has bonded fully I'll go back to rubbing down again.


I've said it before, the least attractive aspect of the K-Series Brick is the water/oil pump and sump. BMW addressed this on some bikes by enclosing the area in the fairing. With the K100RS SE and the K100RS 16 valve they offered a bellypan (at not inconsiderable cost).

They don't often come up for sale and when they do the prices reflect their relative scarcity. Often the mounting frame has rotted away because it's out of sight and out of mind. Both are still available new from BMW and at least one other source but not cheap.

Recently I made an offer on one (unreasonably priced) on ebay (offer declined but more than it's currently been re-listed at), missed one that went at a reasonable price, then last week spotted one that included the mounting frame and had a start made on preparation. I snapped it up for a decent price. When it arrived I was pleasantly surprised to see that it included a sump cover too!

The frame has been cleaned and powder coated after a small repair in one corner:

Will I Never Learn? - Page 2 K1100LT%20%28251%29-L

I don't know if I trust what's been done before it was powder coated. I may strip it and see for myself.

The bellypan itself didn't look bad but primer can cover a multitude of sins (it wasn't done particularly well either) so I've begun rubbing it down (more rubbing down! I'm tempted to go and do a few burglaries as I have no fingerprints at present).

Will I Never Learn? - Page 2 K1100LT%20%28248%29-L

Will I Never Learn? - Page 2 K1100LT%20%28249%29-XL

Before rubbing it down, I had to do something about the mesh grille. On these it's bonded in with some kind of mastic 'sticky'. The mesh has been over-painted with the primer but it's obviously corroded underneath. I warmed the mastic and hacked it away:

Will I Never Learn? - Page 2 K1100LT%20%28256%29-L

Will I Never Learn? - Page 2 K1100LT%20%28253%29-L

Then removed the remaining 'sticky' from the aperture:

Will I Never Learn? - Page 2 K1100LT%20%28257%29-L

I can either re-bond the grille in place once it's been cleaned and painted or I can use castle-nut clips and stainless button-head screws through body of the bellypan:

Will I Never Learn? - Page 2 K1100LT%20%28254%29-L

It will need some tabs to extend the mesh at the fixing points or if I can persuade him, Mark (of Cymarc) may be able to produce an alternative with the extensions for the castle-nut clips in place. 

So, on with the rubbing down of the primer. Sure enough there are some areas that need a skim of stopper:

Will I Never Learn? - Page 2 K1100LT%20%28258%29-L

Will I Never Learn? - Page 2 K1100LT%20%28259%29-L

I'm in the process of stoppering the gouges and scratches.

That's about it for now. I won't bore you with the cleaning of the little bits of various brackets. These and the injector rail will get a coat of black paint before long.

Been side-tracked a little lately but I have been working on it at times, mainly getting the wheels ready for the new tyres.

All the little blemishes that these wheels have collected over the years have been filled and flatted back. That means that sometimes the new primer and paint is rubbed right through:

Will I Never Learn? - Page 2 K1100LT%20%28263%29-L

So the primer - flatting - painting - flatting process is repeated until the final colour coat is okay-ish, then it's on with the clear-coat. That's where I'm at with both wheels ready for a cutting back and polish before the new rubber goes on:

Will I Never Learn? - Page 2 K1100LT%20%28270%29-XL

I've also been attacking other parts like the forward exhaust heat shield - degreased and ready for rubbing down:

Will I Never Learn? - Page 2 K1100LT%20%28264%29-L

Other parts include the brackets for the shield, the injector rail, mudguard straps, spark plug cover, swing-out lifting handle and the rear brake reservoir clip:

Will I Never Learn? - Page 2 K1100LT%20%28267%29-L

The heat shield design is different to the K1 and K100RS 16v in that the two brackets were riveted on, at some stage BMW changed them to screw and nuts, possibly owing to fractures in the shield or rivets vibrating loose. I'm guessing that's the reason but the newer arrangement is a bit OTT. There are rubber grommets with a steel sleeve in the centre plus washers either side. When I removed this one from the bike the screws had been replaced with Stainless Bolts that were much too long. I've raided my supplies for some shorter mushroom headed screws:

Will I Never Learn? - Page 2 K1100LT%20%28277%29-L

Will I Never Learn? - Page 2 K1100LT%20%28278%29-XL

I nearly forgot to remove the masking from the injector rail cups (where the top of the injectors sit).

Will I Never Learn? - Page 2 K1100LT%20%28268%29-L

That would have been embarrassing when it came to start up time.

So next on the list of bits to sort out is this:

Will I Never Learn? - Page 2 K1100LT%20%28271%29-L

It was actually quite nice to pick up something other than a scraper or a piece of grit-paper for a change. Of the main-stand swivel pins, one was dry and one had some grease still clinging on in there. The circlip came away easily and so did the grease nipples once they were cleaned. On the 'dry' end the nipple was blocked completely solid so that explained the lack of lubricant.

Normally I find that plenty of heat on the counter-sunk screws will allow a normal ratchet drive and Allen socket do the job but in this case I had to resort of a breaker-bar on one side.

Predictably, the pivot pin on that side didn't want to come out. It wasn't seized to the stand, it was seized solid in the sub-frame. With the other side out there was enough play to get a junior hacksaw in between and cut through the pivot pin:

Will I Never Learn? - Page 2 K1100LT%20%28272%29-L

The bit left 'welded' to the sub-frame probably will drill out but I have a spare sub-frame so I'll use that one for this re-build and just sling this one out.

Will I Never Learn? - Page 2 K1100LT%20%28273%29-L

Well so much for using some tools, this pile of bits need scraping and rubbing down so that's what I'll be doing again for the next few days:

Will I Never Learn? - Page 2 K1100LT%20%28274%29-XL

Will I Never Learn? - Page 2 K1100LT%20%28276%29-L

I have a reasonably good spare side-stand:

Will I Never Learn? - Page 2 K1100LT%20%28275%29-XL

Trouble is that I think that it might be from a 2-valve bike and they are very slightly different. The difference is enough to stop the stand parking in the correct place when it's retracted. I won't know for certain until it and the exhaust are back on the bike so I'll clean up the one that has come off just in case.

I've an order for bits and pieces in with Ocean BMW, a list yet to be sent to Motorworks and another for Motobins. I find that some parts are cheaper from some sources by a considerable margin. I may have to wait until next month before my finances can be stretched further. At least in the meantime I have plenty to keep me occupied.

nice work on the wheels mike ....
pity some ham fisted tyre machine will grab them  and slice a bit of paint off ...after all the great work

good luck with the rest of the small bits ...fiddly isn't it
sometimes wish I had a blaster of some description just to get through the rough stuff quickly ..eh?

Had I known a few years ago that I'd be doing this stuff so frequently, I'd have invested in a decent cabinet Charlie.

Well my local BMW dealership are pretty competitive on tyres these days, they know how I like to keep my bikes so I don't anticipate any damage to them.

I used to do my own until a couple of years ago but I sold the gear when I thought that I'd only have the one bike. Oh for the benefit of a crystal ball!

I think that the centre stand is probably the worst condition one that I've attempted to clean up. It's heavily pitted with corrosion and the inevitable stone chips.

I began by setting about it with a scraper to get rid of the accumulated mud, rust and the odd flake of the original coating. The side-stand got the same treatment:

Will I Never Learn? - Page 2 K1100LT%20%28279%29-L

Then it was time spent with wire brushes in drills and emery cloth to get to bare (pitted) metal:

Will I Never Learn? - Page 2 K1100LT%20%28281%29-L

I used emery wheels to remove some of the pitting and then when I'd got as near a decent surface as possible, I gave all the parts a thick coat of enamel primer, followed by a heavy coat of the satin enamel. Once cured, I then hand sanded the parts, This meant going back to bare metal on much of the surface, leaving the paint to fill the imperfections. They're far from perfect but better than they looked:

Will I Never Learn? - Page 2 K1100LT%20%28293%29-XL

Will I Never Learn? - Page 2 K1100LT%20%28294%29-L

The finished RS wheels have been shod with new Metzeler rubber and have been collecting dust for a little while now.

Will I Never Learn? - Page 2 K1100LT%20%28282%29-L

Talking of dust, the work on the stands meant that I had to take a day out to strip everything off the shelves to clean-up all the dust that flew everywhere. That's despite scraping most of it off before set about them with the wire brushes.

The stands took so long that in between cleaning and coats of paint, I set about removing the clutch.

As per usual, what, if any, anti-seize prevention had been used on the cover-plate locating dowels had long stopped doing its job. It took a fair bit of persuasion to release it but it gave up in the end.

There's a lot of old friction plate material stuck to oil/grease in there:

Will I Never Learn? - Page 2 K1100LT%20%28285%29-XL

The source of the oil was soon confirmed:

Will I Never Learn? - Page 2 K1100LT%20%28286%29-XL

The shaft O-ring had hardened and was allowing engine oil past. 

Will I Never Learn? - Page 2 K1100LT%20%28287%29

I knew from the lack of the tell-tale smell that the leak was engine oil and I've had placed a bet on it being the O-ring. The output-shaft seal looks okay but it will be replaced anyway (fair bit of friction plate material gathered in the bell-housing):

Will I Never Learn? - Page 2 K1100LT%20%28288%29-L

Will I Never Learn? - Page 2 K1100LT%20%28289%29-L

The thrust washer just slid aside:

Will I Never Learn? - Page 2 K1100LT%20%28290%29-L

With the clutch out there was no reason not to lower the engine:

Will I Never Learn? - Page 2 K1100LT%20%28291%29-L

Then onto the floor for now:

Will I Never Learn? - Page 2 K1100LT%20%28292%29-L

Once I've made space, the frame, complete with steering and forks, can be rolled off the lift and I'll put the engine back onto it so that I can raise it up to work at a comfortable height.

First job will be to remove what's left of the snapped exhaust stud, then the outer casings can be cleaned. I may paint the bare casings with enamel silver to resist the inevitable furring up again.

MikeP wrote ". . . I'll be fitting K100/K75C handlebars, once I've painted them, so I've started to get the controls ready for removal. I've never stripped the bars from a K1100LT before and had never really noticed that the end-weights have a plastic cap covering them. . . . "

Mike, this is the first posting I've seen where someone is lowering the bars on an LT.  affraid 

I'm currently planning the same on my RT (also installing heated grips at the same time).
The big question is; why are you  doing it?
Second, won't the lower bars interfere with the faring?
And thirdly, what are you doing with the slack accumulating in the cable, brake line, and wiring?
