01 YZ 426 Stalls while jumping

Here is the problem.... When I jump my bike, in mid air, it will stall (sometimes). Now these aren't any large jumps either. Just some small doubles and a short tabletop. Everytime I hit the air, it will die.

My son was riding it the other day and complained of it stalling while corning on our berm (left turn). That one only happens rarely though. Any ideas??

I have yet to mess with the fuel screw (just not enough hours in the day). Is that where I should be looking??

im having the same problume and dont know why it happens. usualy if i keep on the throtol a little it stays running.

Hmmm...This kinda sounds stupid but when its running does it die when you turn left or right? We had the decomp lever cable stretch out on my mom's bike and it was really a pain.

Raise the idle!

Yeah, I second the "raise the idle" vote.

I'll give that a shot. Raising the idle... It idles well though. I don't have the decompression lever/cable anymore because I installed the HotCams exh cam. So that can't be the problem. I'll raise the idle a bit and see what happens.

If that dosent do it back the fuel screw out a 1/4 turn, ive also noticed on my o1 that if your spark plug comes loose just a little bit it will stahl like that i rode mine for 2 1/2 weeks with a loose plug fighting stahlling issues I re jetted and everything all over a loose plug..might be something to check...

One other thing to try, try running just the breather hose from your tank cap(without the one-way valve in it).
