my warrior was recently rebuilt, and for some reason when i try to accelerate quickly it seems to hesitate and not pick up speed. I was thinking maybe my clutch slipping? Are there any other problems this could be, or if it is the clutch, how do I go about fixing it? all help appreciated.

 

is it revving fine or is it bogging

 

it revs excellent and doesnt crack at all. It seems fine when I first start riding, but after a while it seems to start messing up?????

 

must be a clutch then
