Sounds like your pilot jet could be too rich or you may need to adjust your fuel screw. If its too rich that could cause it to be kinda boggy on the bottom end.

Heres another good place to learn about jetting: ThumperFaq: FCR Jetting
It focuses on Yamahas, but as long as you bike has an FCR carb it should still apply. Once you understand how the 3 jetting circuits work, jetting is actually pretty simple.
