whats the deal... i cant figure it out... i dont know if its just the sound of the intake or if its something else...

might have a tight intake valve. or an air leak somewhere, does it start good?

started great... i no longer have it... i just wanted to know what it was....

check exhaust seal @ head...

also your cam chain might be stretched and making it almost jump timing.. So id def check valve clearances/ cam chain.

maybe back fuel screw out half a turn and turn idle up a tad more and see what happens also.

i no longer have the quad... im just looking to build another and i notice this skip when i was looking at my old one...

this was hands down one of the fastest quads i've ever owned...

i have access to a GT thunder 460 stroker...
