Sounds like it is running way too lean.

I hate stupid people.

open up the jets a bit (the same amount on all jets)... I will start with a 1/4 turn at a time, you wont know if it worked at idle, go for a ride and shift through gears..

what jets are you talking about streethawk?

Your bike is lean like outsider said... done any recent mods to it?
What RPM range are we talking about? Does it idle ok?

There is NO SUCH THING in an internal combustion engine as too much air. There is however a situation where you don't have enough fuel for a proper mixture for the air present.. If there were a such thing as too much air turbos and the like wouldn't exist..

Check the carb air balance pipes from the top front of the carbs to the 2 spouts at the front in the ram air scoops. Chances are one has come adrift some where or the little filters are blocked with bugs.

For Tech Questions Bike Model letters are more useful than saying the year, for uk owners anyway, as registration year is not always year of manufacturer model.
