Thanks guys, for the insights. The priority for the bike is riding - and primarily pedestrian purposes such as commuting, airport runs, run-about, and probably a few weekend sport-tours. With this project I am playing "free motorcycle" - I previously parted out an R1100RT and parlayed the funds into these two bikes. After selling what I can at the end, I should end up close to zero cost (but that depends on how silly I get with parts and paint). I'll get some pics of the various splines soon.
Meanwhile, today's noteworthy progress is: footpeg plate subassemblies. Powdercoated plates, levers, and passenger peg brackets, Spiegler braided brake line, painted master cylinder (all non-ABS parts from parts bike). Removed ABS pumps and brackets - damn, you would
need ABS to stop the bike with all that extra weight.
A lot of stuff on the '92 is corroded. I had to resort to a sledgehammer and drift to get the pin out of the LH rider peg - miraculously without damage to the ABS peg-plate.
