Hey Guys, I just bought an 01 yz426. Here are the issues I have with it: -Only runs with the cold start pulled out. As soon as I push it in the bike dies. -Popping or snapping and flames coming from exhaust. For performance it has a DR.D full exhaust and a k&n filter. I was thinking the jets are too big and its drowning itself. I know for sure that the MAIN JET is a 180..Is this too big??? I'm not sure what the size of the starter and pilot jet are. I live in AZ and the elevation is 1200 ft w/ and average temp between 80 and 90 F. ANY suggestions would be appreciated!! Thanks!
