I've been having problem after problem with getting my motor running just right since i rebuilt the engine. Right now I have compression issues. But anyways, I have a stock cylinder and head bored .60 over from stock, with a forged piston and high compression gaskets. As of right now, I'm still running my stock carb with this and its been giving me problems. I went through Vito's to bore my cylinder and they supplied me with the forged piston and high comp gasket kit. I also got the Vito's 2stage carbon fiber reeds. ONE DAY of riding after all this was rebuilt & broken in and I snapped a reed. I think it was because my engine is demanding a quicker or higher airflow and my stock carb cant deliver. Does anyone know what size carb i should get? I was thinking 30mm..
