2004 crf 450

I have a 2004 crf 450 that I was driving today when it backfired and quit... when I started it back up it will only idle if I give it any gas it will backfire and quit? I took the carb apart and all the jets are clean timing marks also seem to be spot on as far as im aware of.

Did you check the air jet in the intake bell for contaminants

Is you air cleaner spotless

Is your fuel water free

Yes I checked it all.. it all started when I forgot to turn the gas on and it backfired and quit

Have you cleared you cylinder (kill button on, throttle wide open, 15 short rapid kicks) then try to start  again?

what he said, and you checked jets, but are you positive the pilot jet tiny hole down the middle is clear ? it's easy to see the 8 holes on the side of the pickup being clear, but there is a tiny hole down the middle too like a main jet.

Also need to check for voltage. will need a special adapter for the multi meter to check. need 50vt output. mine was doing something similar and was putting out 35vt
