here is a picture of my R90/6. It has been off the road for five years after a small accident made me decide to do some renovation work. I am just finishing the adaption of the silencers to a glass packed exhaust system like the one that was designed by Jim Cray. I hope it will not be too loud.
Sam, you've obviously put a lot of work into the bike. K front end with 4-piston calipers, Dells, late model gearbox, yet still on spoked wheels and with alloy indicators. Nice.
"Be careful about reading health books. You may die of a misprint."
I have put a fair bit of work in, but Jim Cray is the one behind the brakes and engine improvements, he is based in Kent in England and is very skilled. I had the bike running with this 1992 K100RS front end and R1100s brakes for a few years, but as a sort of ratty cafe racer. I want to return to more of a stock look when I put it back on the road. By the way, these calipers work really well with the under-tank master cylinder.
I am away from my bike at the moment and so will have to do this from memory.
The front rim is as far as I remember an 18" x 2.15 (rear is 18"x 2.5)
The hub is a four-fin R-series,
305mm floating discs are also R1100rt (same as on the K100RS 1992)special disc spacers were made by Jim Cray
Metal was milled from the mounting tabs of the R1100rt calipers (to correctly position them)
Axle spacers and clamping sleeves made up (It uses the 17mm axle in the K100RS 1992 fork so sleeves are necessary).
This front end was put together some time in the late 1990's, I can't remember exactly when. It was a real fiddle to assemble and fit, so after buying the parts, I entrusted the job to Jim Cray in Sittingbourne.
The one thing that I really wanted to do was keep the under-tank master cylinder (17mm). Jim said to try it and see. It works beautifully with the four piston Brembos and this front end, with vastly improved brakes, changed my whole riding experience for the better.
Hello Sam, I've got the Project bike to an almost complete state and just need all of the fiddley bits done but I have run out of steam, but I've replaced my 60/6 runabout with a '89 R100 monoshock that I am playing with and that's why I asked about your front wheel, I have a set of K75 forks that I shall upgrade to 'S' spec to replace the Mono front end but I have also picked up a pair of K1100 fork legs(are thy not the same as your K100 16v forks)and a R1150 front wheel - that seems an easier root to take than the one you've taken with Jim - but then you'd of had to use the late rim with the outside spokes that would match the I'm rear GS hub I'm keeping my eye out for. What was so difficult in fitting the forks? Your look as though they don't have a lot of travel - is there enough? And finally how is your Paralever project comming on ?Cheers.Martin
The fiddly bits are the killer. I know all about running out of steam. Plus, for me at least, working on more than one project at a time means that no one project is completed! At least you have the R100 monoshock to ride. The K100rs forks are very very similar to the K1100 forks on the outside, but the internals appear to be different. I've just re-checked (on bmbikes.co.uk) what the travel is supposed to be: 135mm, I may have the forks too far up through the yokes in the picture as I have had the forks off recently.
I wanted to keep the traditional spoked wheels, hence the complication with front end assembly. Also the forks are physically much longer and the early R-series mudguard is not an easy fit. What you are doing is much easier and probably better all round.
The Paralever project has been shelved for the moment. I might even sell the accumulated parts and keep only the modified frame. I am short on space, time and money, so when I come back to this project I could buy a donor R100R perhaps.
Best wishes,
Sam

Sam, does that muffler get more closely aligned before welding or are you going to fill it in with welding rod?
Hee hee. I could have tried to photoshop it into position, but I thought I would save that time for the actual job. I have it on there at the moment as I was trying it for length, the headers are a bit long at the moment. Cheers, Sam
The exhausts are welded up, the loom is back in, lots of other small jobs have been done.
The oil tank is moving on all I need to do is to plumb in the hard lines to connect the exhaust sucker valves (red and green knobs) to the reed (under that cone at the top right of the first picture) and make all other connections: exhaust sucker lines to exhaust pipes, oil returns to sump,etc. and make a lid for the tank.
I still need to finish the battery tray (modified for smaller battery) fill up all the fluids, get it started and do some carb balancing and other troubleshooting and then get a MoT test certificate.
I think I am starting to believe in Feng Shui as having this non-working bike in my workshop definitely puts a downer on the mood of the room. One it is up and running I will feel much more positive about the place.
