Zip 50cc what rollers should i put in

atm im not sure what rollers i have i think they the ones that came with my zx exhaust,
what weight are these? cratch:
im hitting 45mph with these rolllers with a quick acceleration?
i want a slower acceleratiopn and quicker top end speed what size rollers should i put in?
i have a piaggio zip 2002 50cc

 

you obviously need 2 put in heavier rollers then. So take the old ones out and weigh them. and buy heavier ones.

 

heavier rollers does not increase top end., U need about 5.5-6gm rollers for this setup make sure been upjetted

 

I have the same setup, zip 50 with zx. my zx came with 4.8g rollers i think. i get to about 55ish (speedo stops at 50) and my mates can go about 5mph faster on different peds than me but i accelerate quite a bit faster than them. I was also wondering if it is a good idea to up jet it, will it make a difference? and also will a new air filter make a difference?

 

no a new air filter wont make a difrence and no u shudnt upjet and bradley has ur zx been de restricted as im sure when you buy these new they have restrictions

 

yer most sport pipes are restricted only to make them road legal
