wassup guys!!! got couple questions for you guys. first off i just got in to peds not to long ago. I bought a 2010 Sym DD50 that already had a 66cc, ramp, weights, pulley, belt, cdi and performance coil. Im getting about 50mph not bad at all but want a lil more. I was thinking of the 72cc Polini Contessa. Brand name and cheaper than the Corsa. Is it just a bolt up/replace all the parts in the kit? what about carb/manifold, do i have to change those to performance? and gearing can i run my stock gears for now til i decide to change them? Money is limited and just want to build it a lil more 72cc Contessa for sure...what else do you guys recommend? Aloha and thanks for any help you guys can give me.
