Do you have the same carb?


120 main sounds about right, I ported the intake path to match the carb opening and have a open style air filter, free flowing exhaust. Other than that it's stock.


So I'm guessing I'm on the right path. Maybe a 35 Keihin pilot might be worth a try. How many turns is your air/fuel about and what is your needle clip on? I'm just trying to reference to ball park mine? I'm shooting for 1.5~2 air screw, sound about right?
