xr50 to xr70

Would i be able to just by an xr70 piston and cylinder and bolt it onto my 50?

hmm no

youll need the xr70 head to do the swap, and denn youll want the cam and carb too.

so

its cheaper to buy a trailbikes 88 kit, it will be way faster too

i made the mistake of trying to cheap out on the bore kit the first time, got a 72cc kit with a flat top piston that was nothing but trouble. finally blew it up and got what i should have gotten in the first place.

k thanks dude
