Hi, my bikes a yz490. I'm only 150 lbs, but I can start it 3 kicks cold every time. Hot starting is the trouble. It can take anywhere between 2 and 20 kicks. it usually takes around 5. It runs a 40 pilot jet, 290 main and needle clip it the middle. The plug is light tan and there is no oil dripping out the silencer. It doesn't seem to matter what I do with the throttle, it starts the same. Sometimes it backfires before it starts. I am rolling to compression then kicking hard all the way though. Please give me some advice.
