Description

This bike was born in 1977/78 as a red/smoke R100S. I bought it in 1999. Portner’s paint shop repainted in 2002, but the first day I parked on the street, someone side-swiped the fairing, cracking it and chewing the paint. The speedo/odo didn’t work when I got it, and PA Speedo rebuilt both speedo and tach in 2003. I estimated about 35k miles, but had the clock set at zero by PA. They didn’t notice a bad jewel in the tach, and I had it redone in 2015 by Foreign Speedo. The clock works. Numbers match.

Always in love with the “Last Edition” paint job, over the years I gathered the fairing parts to turn the bike into an RS. In 2015 I found a master painter and bought the Glasruit spec Pearl White paint. The result is what you see. The top end was rebuilt by Bob Grauer in 2007, with lead-free valve seats.

I recently took the bike on a 2,200 mile ride. It used about ¼ quart of oil in that time, and got 46 miles to the gallon, despite some spirited riding. The brakes are as good as most modern bikes, with the new bar-mounted MC and Spiegler floating discs on the front, and new MC and rebuilt caliper on the rear. (The photos with the bags are before the front MC was changed and the Spiegler SS lines and discs installed) The rear main seal was just changed, with other gaskets (oil scavenger, etc.) and neutral switch replaced. Newly powder coated rear rack. Tires relatively new.

Easy pull clutch installation is a dream. Dyna ignition. 96xx miles since the rebuild with new clutch plate and disc.

Problems: I cannot find the rear R100RS badge or the “Last Edition” battery decals, so the R100S is still on the tail, and the battery covers are nude. I have not moved the wiring from the headlight shell to the dashboard for the ignition. Key is still operated from the side of the light. One chip I caused (image) and one tiny defect in the paint job (image.)

Front suspension needs some tweaking: excellent compliance up to 75 mph and then a bit of a bobble.
