I've got a problem that I hope someone can help with. I've got a 2001 Raptor with a ProDesign K&N intake, Dynojet kit, and Gytr pipe. I've got the jetting at Dynojet specs, I think its 144, 146 mains, stock pilots, 3 turns out on the screw, clip in 4th notch.

The problem is this: When I do a wheelie from a stop (popping the clutch), for a short time and then pull the clutch in and let go of the throttle to bring the front end down and come to a stop it will sometimes stall. I called Dynojet twice and got two answers: 1. turn the air screws out a litle more until the condition goes away 2. Put the needle on the 5th notch. I haven't cleaned the air filter yet but it doesn't look too dirty. I've also got some 25 pilots that I could put in. What do you guys think? I live in Texas and ride at sea level. Other than that, it runs great. Thanks.

 

check ALL your carb hoses. make sure there are no creased places along the hose. happened to me a while back.

 

It sounds like its not getting enough gas, it might be the float height. Did you happen to touch the tab on the floats?
