Does it bog when you wack the throttle from an idle or anythime? Sounds like you need to start by turning out the pilot screw a half to a full turn.

[300EX_HMF]

yeah it bogs from idle! and where exactly is the pilot screw and do i need to mess with the main jet???

The air/fuel screw is usually on the bottom of the carb.
