Anyone know if a shaft drive rear end can be installed into an XV920RH? I have a line on one that would barely get me past the 33% mark of the Cheap Bike thread but it is jumping out of 2nd gear. The bike looks immaculate and has about 32,000km on it (~18,000 miles). Sacrilege! Yeah, I know, but swapping in a good 1100 motor and 1st gen monocross swing arm seems like less of an arse ache than splitting cases. !
