All back together, teeny shroud bolts now coated in anti-seize... Hopefully the heatproof black will stay on the shroud for a while.

I just used Rustoleum satin black on mine and it hasn't been heat effected yet. So heat proof will definitely stick.

Brilliant paint but not sure how it works. Used it on part of the frame of my K100RT in 2013 and still looks like new. Used in on my heat shield and not so good but I used bike in winter and there is salt ends up trapped under it. My RS got a new heat shield last summer and it wasn't in great shape when I swapped it this time for another brand new one. Might put Rustoleum on the now old one as it came off in one piece.

I love the disc, mine was one of those too ....while you are there with that heat gun crack out the two bolts holding the disc on and put them back with anti seize.....

Another job done, all 3 callipers overhauled & refitted. Not without some drama, the overhaul kits were bought from Motobins that quoted a kit (Ariete branded) to suit early K100 and some R series, so without any thought I ordered the 3 sets. HOWEVER on rebuilding the first calliper the pistons/pots refused to pass through the new seals, at first glance the old & new seals looked identical size wise - both to suit 38mm pistons, however without a set of digital verniers to check it was impossible to tell if there was a difference in seal profile size. The following corresponding OEM number is quoted by Motobins for the Ariete overhaul kits, however after researching that BMW number it appears it is ONLY for various R series:  

34 21 1 237 234  

So, after scratching my head (and feeling a tad cranky) 3 more sets of overhaul kits were ordered, this time genuine Brembo kits with the following corresponding OEM number:   

34 11 2 310 493   

Which DOES match the BMW recommendation for the early K’s.....and fit perfectly. My guess is (without measuring with callipers) is that the K100 calliper seal relief is marginally shallower than an R calliper....or is it an Ariete thing? All I know is it is appears to be impossible to use the Ariete kit seals. 

You live & learn, to check & check again. Rolling Eyes 

Much better....

Very annoying indeed, serves me right for not checking the OEM numbers I guess. 

BTW Motobins have refunded the kits, can’t fault their service in that regard.

The rebuild progresses, After all external fuel & vacuum hoses/plugs were replaced, the original injectors had a birthday by being cleaned & tested, all 4 were pretty much in spec surprisingly & flowed pretty much the same, albeit still being full of crap. 

On first startup after the external work she still wasn’t too happy until warm and took several hits of the starter, and throttle could not be touched. I was putting off changing the in-tank filter & piping until the tank was painted, but gave myself a slap and pulled the filter....she was shagged, you could barely blow through either way and had a manufacture date of 22/04/03...Shocked not to mention the rubber lines perished and swollen. Funnily enough, after the in tank work she started up first hit of the button dead cold. Not enough pressure for a cold start? 
1983 K100 RS Project - back to the 80’s - Page 2 A1e86010

The build’s now at the far end, with the brakes to finish off, tyres, battery & fresh paint. 

And yes Martin, you’re tuning skills may have to be booked in in the near future Very Happy

Dan

Ok thanks Martin - I think the seat (early pattern with the hand holds) is actually in reasonable nick, but I'll def keep that in mind if it turns out not so. 

Your spare seat turned out great, very impressed. Don't know about the thought of you three playing around with vinyl though - sounds suss Shocked

The rear shock was overhauled by RAD on Brisbane’s southside (thanks for the head’s up Mick & Co), new Avon hoops front & rear, new rear brake reservoir, master cyl overhauled, pretty braided lines front & rear, etc etc

Pretty much now on the home straight - a battery to be purchased, the front master cylinder to be re-kitted (I KNEW it would start bloody weeping the minute the front brakes were bled....) then it’s time to start thinking about paint I guess.

Ah, good spotting.... Cool  I did try to reroute the headlight harness as per the Basic K100 spec, but it seemed like the RS harness was shorter & it was too stretched...may have been me of course, perhaps if I had cut every ziptie in the harness I may have had a bit more room...oh well, next time...

Finally got around to fitting the RT/LT bars & pad I sourced from kmodelbeamerbits. As well as the bars the old girl got all 3 cables replaced (which I should've really done a while back) and a longer front master cylinder line down to the steering stem.

Man, that turned out nice! Would like to know your process for cleaning and polishing the aluminum. The paint job looks amazing as well. Would like to have my RS redone but I'm afraid the cost would be more than the bike is probably worth even though it's in great shape.

A local body shop wanted $600 just to do my black belly pan I got from Flat Racer. Jeez!

Hi All, thanks for the kind comments.

RS Rider the aluminium cleaning is via other's members tips on this forum - stainless steel wool, water & sunlight soap, followed by a wipe over with Inox from time to time. Seems to have kept clean so far. 

Agree with MartinW, GB777's spray job looked pretty good to me

 Martin,

        Would you happen to know what brand he used? I’m thinking about getting RS aerosol from the UK (they do ship to Canada) and then trying that on some of the smaller pieces, such as rad shroud or front fender. The only thing is that I would want the 2K clear which is nasty smelling stuff. I have a garage but it is attached to my townhouse. I don’t know how well spraying that stuff in my garage would go over with my neighbours.

Ideally I would like to find someone that has a set-up at home and would do the work for cash and I would supply the products.

Tom

In the past, I have done the prep and base coat on my parts and then taken them to a professional collision shop for the clear coat.  If you ask around, you should be able to find a shop that will shoot the clear for a reasonable price. 

The big part of any paint job is the time that goes into the prep, the actual work isn't rocket surgery if you take your time and don't cut corners.  By doing the prep you can save as much as 80% of the cost of the paint job.

The only important part is to shoot your base coat within a day or so of when the shop can do the clear.  This is to get the best bond between the coatings.  You can do everything up to the primer and then have the shop let you know when they can shoot the clear.  Then do your base coat and get the parts to the shop for the clear. 

I had a local shop clear all the painted parts for a K1100RS for $150 and a dozen donuts for the shop crew.  The finish was better than I could have done with my Harbor Freight gun and didn't require any more than an hour or so of buffing to look fantastic.  It's amazing how well a 40cfm compressor and a $300 gun in the hands of someone who shoots 5 days a week can apply paint.
