i just got my polini 70 kit for my speedfight, im doing a few other things to it, what size jets will i be needing and what weight rollers would be the best for doing wheelies ? :w00t: cheers dudes
ur going to have difficulty wheelying a speedfight mate there so heavy, my mate has one he put 5gram rollers in hes and they where way to light try maybe 6g 7g or 8g all i can help you with
how about buy a few sets and try them out for yourself, its very hard to set a bike up from opposite ends of the uk mate, and please use the search i really am bored of roller/jet questions.
