1982 -1990 will fit.Most of the big inch Buell rear and front motor mounts have same frame bolt patern also(not that it maters could come in handy down the road though).
You asked the differance in rear motor mounts, no not in mounts themselfs. Yes there might be a very small amount of tweeking,drilling here and there but it will be very minimal,but I doubt there will be any at all.******* Smooth said:So, I could put my '83 Sporty motor in an evo frame with minimal mods to the frame itself? Holy shit, I'm gonna build a chopper this winter...
