I’m selling my 1975 R90S after a semi-restoration process. It has triple matching numbers, and I have made everything functional and clean, although some things have not been touched in 47 years and 31+ thousand miles. Restored to its original state within reason. If it weren’t broke or ugly, I left it alone.
The Old: Engine, transmission, and drive line are unmolested except for changes in lubricants and tune-ups. That said, the engine still gets 130 pounds of compression in each cylinder, and it starts and runs like a champ. With highway driving, you will not need to add oil between changes. The frame has been touched up wherever it was rusty or funky, but otherwise most of the paint on it is original. Many assemblies have been overhauled, such as the stabilizer rack and pinion, the petcocks, steering head bearings, etc. The clock and voltmeter work. Wheel and final drive splines are in great shape. Pushrod tubes have rust on them, but they don’t leak.
The New: New Daytona Orange paint and proper pinstripes; rear sub-frame and battery box powder coated; rebuilt brake hydraulics and new pads; re-upholstered seat; new spokes, tubes, and Bridgestone Battlax tires; MAC exhaust with less than 3K miles on it; new carb floats, accel pump diaphragms, and seals; new fork seals; fresh fluids all around.
Better Than New: Starter cable upgraded to #4 welding cable; Mega Crank AGM battery; electronic voltage regulator; engine breather valve updated and custom-made splitter tube; Dyna III ignition, Bosch blue coils, NGK iridium plugs and wires; air horns with under-seat compressor (nice and loud); body work lined with matte black paint instead of overspray; Zero Gravity windscreen; stainless spokes on rebuilt wheels; many parts polished better than factory, such as handlebar mounts, instrument bezels, and oil dipstick. The master cylinder was re-lined with brass to eliminate corrosion. Gas tank is from a /7, with the breather out the bottom, so your tank bag doesn’t fill with fumes (It would be correct for a later 1976, but it isn’t for this bike). Bar-end mirrors give you a blind-spot-free view without the shakes of the OEM mirrors.
I have spare parts of various sorts. I also have a set of BMW factory bags and an expandable BMW tank bag, as well. They are not included, but if you pick up the bike and bring some extra dough, we can make a deal.
I have many more pictures on a website, to which I will provide the address upon request.
