Hi, I'm James, I have a 2003 Piaggio NRG Extreme *Old Shape* i have a Doppler S3R pipe for it that i still need to fit, Dunkno if its rollers or Jets i need to change, still waiting for an answer as when my mates was fitted the bike tops out at 30, and then bogs! I have stock rollers, so thinking of getting Polini 4.3gr as i've been told 4gr-4.5gr is spot on for NRG's I'm from Kent btw :yahoo:
