Ok guys, heres my delima. My bike is an 03 WR450 I can not kick start the damn thing. Long story short jetting has been gone over 1000 times, there is nothing in the jetting that has made any bit of difference in the way it starts. current settings(i know they will be asked) Pilot 48, 1.5 turns on air screw, 168 main. all the others are stock. If i let the bike sit over night, i can walk out choke the bike and start it in 2 kicks. once the bike has been running and i stop I cannot restart the bike. I can kick start it till my foot is numb, and cannot get it to refire. If i roll start it its almost instant start up. I am to the point of wanting to torch the bike. I cannot figure out why it wont start. on occasion i have trouble starting it cold, but that is rare. its 99% of the time when its hot i cant get it restarted.
