My stinking bike has been having issues since Moab. It is a 2000 WR 400F. When I run on the top for an extended amount of time (like on the highway or screeming accross the desert) the stupid thing dies like it is out of gas. I try to coast start it, and it doesnt work. Just acts like it is out of gas. So I kick it, sometimes it starts with in 3 kicks, other times it takes 30 minutes. I took the carb off and cleaned it as best I could and no go. My brothers 2002 DRZ400 has been doing the same thing since Moab. He tried cleaning the carb really thoroughly too, and no avail. Any ideas? I cleaned the air filter of course. Is there something in the carb I should look at specifically? Thanks for all the help!
