I just picked up a used 1993 JR50 for $100. I was wondering do they make stroker kits for these to make em more fun to ride? Or any performance parts to give em some bite.

im not sure about the 93, but the newer JR50 and KDX50 have a hidden 1st gear that can be activated by dremmeling a notch out in shifting shaft. look into it.

yeah will work on the older ones too. You should be able to overbore it to 60cc's. Add some compression and they are sorta OK. Not exactly designed for performance or big guys though.
