Hii everyone, thanks for the warm welcome to the forum (especially Martin & the other aussie K members), the info available here is quite staggering, to a total brick newbie like myself i dare say it’ll prove to be be invaluable. 

I thought I would kick off a rebuild thread here rather than forever extending the new member thread.

After pondering on a project bike for 2020 I was considering an early CB750, however I’ve always liked the look of the K and thought it may be a nice & (I hope) somewhat reliable alternative. As my usual ride is a boxer I also thought the laid-down 4 would be a change. 

I’ve had the K home for a week now after spotting her on the ‘net, she was destined to become another cafe racer or spares bike😱....I’ve always liked the look of the “standard” K100, so the plan will be to backdate her to that spec with an original appearance. The RS fairings were pretty knocked about, so I wasn’t really tempted to keep her that way. She’ll be kept as Madison Silver - I thought it was originally the solid silver tone, but was pleasantly suprised😀

Specs:

12/83 K100 RS
Madison Silver
Condition? Running....but rough. 

Anyhow, here’s the pics so far- 1983 K100 RS Project - back to the 80’s 48668810
Pickup day😀👍she made it onto the trailer under her own power too.👌

A nice surprise today - first aid kit, circa 1983

1983 K100 RS Project - back to the 80’s 0db8b210
Manky fuel drained today, fuel pump & damper relatively intact I hope?🤞They’ll be both replaced anyhow, but I was happy not see a complete mess in there....

Safely home. The side covers do exist, just off!

Over the next few months all fluids will be changed, components inspected & replaced as necessary, wiring sorted & then onto the bodywork. At least that’s the rough plan at this stage. 

Hope you all like. 

Regards

Dan

I've brought more than one old K back from the dead and one of the first things I always do is pull the fuel injectors and get them refurb'd.  Doing that, putting in new spark plugs (NGK D7EA) and synching the throttle bodies usually gets them running like a top.

Good idea to respect the genuine appearance of the K!
I'm also building a K100 racer using only parts that were available in the eighties, from BMW or aftermarket: Fallert seat, Recchia (French BMW dealer) exhaust, ABR footpegs, telefix fork brace, Ohlins shock...

Cool another  Brisbane rider   or have I all ready said that  ?  

Anyway best of luck with the bike there is quite a few Brisbane people on here if you need a hand  

I have used the  Truck Bull Bar Wash  from Bunnings to clean out  the varnish from a few tanks 

it even cleans out the black goo for the pump ring if it has gone bad  

What side of Brisbane are you from ?

Thanks Mate, looks like the tank & pump have been done some time in her past, luckily not too grubby. I have bought some submersible fuel hose to replace the intank hoses though. 

Brisbane Northside, Stafford area. 

Another purchase arrived today:D(it’s for a slightly later K I know, but was a dirt cheap pickup off fleaBay)

When you get to the tune up stage give me yell. I have a set of vacuum gauges and a exhaust gas analyser. I also have a good selection of specialized BM tools. If you ever need more submersible hose try 
http://www.motorsportaccessories.com.au/ in Brendale around $17.00 a metre if you become a member. They also stock the correct size EFI hose clips. Membership is free. 

Bunnings stock K-Flex hose insulation approx $5.00 a metre which is a worthwhile addition to external hoses especially in QLD. It is a tight fit and requires a liberal dose of talcum powder to slide it on.
Regards Martin.

Great tips, thanks. Yup - that’s where I got the hose😉👍cheapest around I found, by far.

 I’ll definitely book you in for the tune up, hopefully by the time the cool(er) months roll around!

It must be a Qld thing 😂. The refurb on my K100 RS has just begun, same colour. On the to do list so far is fork seals, rear main seal, new clutch, check all rubber, replace all fluids and the other typical service requirements. Hopefully on the road before Christmas, anyone in for a SE Qld meetup?

Hi Standard K 
From one standard to another Hi.
I have a 1983 K 100 stock as a rock and found the first aid kit under the seat as well. 
I am located on the south side of Brisbane in Salisbury. 
The biggest problem I have had was the fuel regulator decided to shit it self and unfortunately I was in Longreach, Thank god for RACQ gold cover. 

Would love to hear from anyone that can help me balance the carbies please. 

Regards

Ian

Ian tune up is not a problem as I have all the gear, just coordinate with Matt and Mick67. Before doing the tune up it pays to check your valve clearance, status of the "Z" hose and status of the throttle body vacuum caps.
Regards Martin.

Hi Ian, I am but a Standard-wannabe at this stage....although I have now managed to acquire (as of today) a standard headlight assembly & the radiator cowls.  cheers

Would LOVE some allover pics of your bike & also the radiator cowl attachment points!

Couple of hours spent today removing RS brackets etc to fit the Standard radiator cowl, did a quick mock up of the desired look (minus side panels), gave her a new set of plugs & fired her up. Plugs removed were D8EA? As expected the plugs were pretty wet, I will probably pull the injectors over the next week or two. 

Pretty happy with the backdated StandardK! bounce

A few leisurely hours spent this morning on the K, I managed to strip off the tank, rear cowl and other bits & pieces. The wiring looks pretty much untouched & not butchered, however there’s a little surface corrosion on the frame underneath the tank (due to the heat-proofing absorbing moisture) I’ll have to tidy up. 

The Z-hose was that loose & barely hanging on it popped off in my hand, not really surprised now why it was idling rough!

G'Day Dan,

Good to catch up at the workshop day (nearly said hook up...but it means something different now!!)

As your Z hose was perished, will be a good idea to check/replace vacuum line to FPR  - comes of take off valve closest to seat end of rail and follows fuel line from end of rail to FPR behind lower half of air box. You may also have a 'pressure switch' behind the throttle bodies - pre 4/85. A vacuum line from this follows the fuel return line around to the front of the throttle body - would be good to replace this as well.

Let us know if you need a hand...is a fiddly tight space....I am not far away from you...and have just been schooled by master Martin on the procedure.

Cheers

Mick

I certainly won’t be boring everyone with pics of every single bit & piece cleaned up, but I thought I’d kick off proceedings with the very first bit, namely lower airbox.

Before:
1983 K100 RS Project - back to the 80’s E705ea10

After:

1983 K100 RS Project - back to the 80’s C1192910

After 30+ years of filth & a fossilised Huntsman spider were removed with soapy water the silver overspray was removed with lacquer thinners, then cleaned with Meguiars paint cleaner, followed by an interior detailer. The snorkel grommet was removed, cleaned and hit with the detailer. Surprisingly it became somewhat supple again.

Regards

Dan

Motor degreased & cleaned up somewhat of 35+ years of road muck & oil misting out of the split Z pipe.

Lots more cleaning & steelwool+sunlight soap treatment to come! 


Smallest reg brush measured up at 6mm, so new ones to go in I think.

The dreaded Monkey’s Nuts were in surprisingly good nick. 

1983 K100 RS Project - back to the 80’s C6b1b310

Also managed to clean up the corrosion under the tank (caused by the heat absorption matting) and was happy to find nothing serious at all, just some light pitting. Sealed off what little corrosion there was with rust convertor, and will be touching up the frame to freshen it up.

Slid the box back today to inspect the clutch, as I knew that it would be in the back of my mind if I DIDN’T have a look...I already had the Alt & Starter out anyway.

Glad to see clean splines (albeit dry), they appeared to be in pretty good nick too.

Ah! That’s better.

Now it’s onto the cleaning phase, and inspecting & replacing as she goes back together. Still enjoying it!
