Hi guys, i put a sport exhaust on my Aprilia Sr with a 17.5 carb. I think i need to put new lighter variator weights and different clutch spring's ? Maybe someone knows what kind of weights and spring's i should select ? Thank you guys in advance.
What he said^^^ Also, have you gone from standard pipe to sports pipe? If so you may need to re-jet the carb. More details please.
I've gone from standart to polini for race sport pipe. I restricted my carb and it has 62 main jet, do i need upjet it, and what jet i should put on ? Everything else is stock. btw. my carburetor is 17.5mm by dellorto
