Sounds like a broken record in here..... but you do need to rejet [img]i/expressions/face-icon-small-tongue.gif[/img]

 

You also need to ditch the big gun slip on, I had one...it was worse than stock, way freakin loud....no freakin power.

 

Wow, k&n, no lid, and slip on without jetting up. That is definetly not the best for your motor. Jet up and see what happens to that blaster....[img]i/expressions/face-icon-small-happy.gif[/img]

 

this is deffinately a jetting problem. The GYTR jet kit should show you what jets you should use for your elevation. After it has been jetted right, if it still seems like its not pulling like it should be try moving you neddle clip up and down until you get it tuned in. Bottom line....your raptor should be blowing those quads away.
