    I've got this thing in my head to find an RS or RT rear hub to put on the 91 GS, try to get the engine revs down a bit. Anyone try this?? How available are these hubs out there? I've never had any problems with that portion of the drive system [gearbox & driveshaft, don't get me started!], it's probably be off a wrecked one.

    You'll need to modify the pinion. The Airhead Paralever pinion spline length is only available in the two ratios (3.09 and 3.20) that came on those bikes.

    Would have to be an internals swap, with the requisite re-shim, etc. No Paralever housing ever came on a RS or RT.
