SSR 125 with 22M Mikuni Round Slide Carb. My 25 pilot jet got smashed in the carb when tightening down and didnt have any smaller jets on hand which is what I needed but riding in sub freezing temps the 30 pilot was do able. Still got a bog if you snapped the throttle to hard which could compensate with the needle clip but still the 35 would be to big. Good quality jets from Tbolt.
