What are you using for intake/exhaust? -
At what rpm and throttle position does the hesitation show up? If it show up at medium throttle settings, during roll on acceleration, you might want to shim the needles.Ed
To measure is to know.

I use 4-1 and stock airbox,It starts from about half throttle and up under acceleration.Comment

It is probably lean due to the pipe, go bigger on the main, maybe raise the needle more, and do plug chops until you get it perfect.Comment

Dont under estimate the importance of rebuilt carbs.
If the carbs are perfectly clean I'd say you need to raise the needles but ya have to make sure the needle jets are clean clean clean clean...Comment
