nothng lower than a 175 w/ the airbox lid removed. if you put it on, it will run like ****. oh yea...and that is below 3000 feet

pilot jet i think would be about a 48? but dont quote me on this one.

now the air fuel screw is up to how your quad runs and ****...it all depends on if it is running a bit lean, or rich.

oh yea...these are dyno jet #'s
