my polini sport 70cc kit

can i put my 70 kit on my yamaha slider and keep all of the standard parts for it like the exhaust, crankshaft, carb and air filter or would i have to buy new parts to make it work.

 

Ideally change the carb and exhaust to get the most potential but as for the crank it should be fine

 

i wouldnt say the crank would be fine. you're better off getting a full circle crank as standard cranks aren't as good. i think you might be able to use crank but it depends how many miles it has done. on top of what pow said you're best off getting better gearing to enhance top speed.

 

but as far as i know you can use it with standard components without damaging anything it just means it wont be as quick.
