Background: 06 kfx 440 Jetted perfectly on stock 06 carb Hotcams Big Gun CDI Rev Box LRD Full Exhaust Has about 200 hrs on this setup. Oil changed regularly. Has a fresh oil change with 10 min of idling on it. (come to think of it before changing it it seemed to die after a few min of idling to warm up, but I thought nothing of it and changed the oil.) Sat for 2 months without being ridden, but ran perfectly when parked originally about a week before the oil change. Went to pismo and it would not run after a 9 hour drive to the dunes . Spent the weekend trying to fix things with no improvement. Before I left the bike ran sluggish, but ran enough to load it.(MISTAKE) #1 Needed choke though. Symptoms The bike will turn on and idle normally with choke on about 1/2- full choke for about 3-4 min then die on its own, but the second I even touch the throttle even a hair it instantly dies. No matter if on prime, reserve or on. 91 octane gas is still old and I did not use sta-bil. Wouldn't it not even start if the gas was totally horrible? What I've done so far -Cleaned the main jet and pilot jet with carb cleaner. You can see daylight through the holes. Even before cleaning everything looked new. Float did not seem stuck at all. -Unplugged CDI and plugged back in -Grounds are on tight. -The little wire near the throttle is plugged in (not sure what it is even) -All hoses are attached to the carb. Including the air box and hose from intake port to carb. -I blew air through the petcock tube into the tank using the healthy choice of using my lungs. Gas flow didn't seem like a river coming out of tube, but about a stream. -Even tried starting with gas cap off. No difference. What do you think I can do? I'm so lost and frustrated. I've had 0 problems with this quad until now. My k&N filter seems a bit dirty though, but I don't think its enough to make it not run.
