my 07 450r special edition has had a stalling prob. since the day i bought it. it happens after blowing across a field wide open or suddenly stopping, engine stalls then i have to crank it for about ten seconds,then it sputters back to life . any ideas????????????????????



i have a ton of upgrades but none of these seem to help, no matter what i do it just wont go away

 

Sounds like the fuel screw needs adjusting. It's a pain to adjust the stock one, so get yourself one from MSR the you can just reach down and make fine adjustments while sitting one the bike.
