pulling away ?

i recently fitted a 9 speed polini variator, torque spring, kevlar belt and malossi clutch and my bike seems to pull much better but as i pull away it bogs then kicks in im just wondering if anyone knows how to stops this. im running it with standard jets and aribox could this b causing it ?

thats why!,you need to at least jet it for that pipe. if you put a standard pipe back on it would run smoothly without and flat spots or just jet the carb for this pipe i would hazard a guess of about a 70 main jet for it.
