I just recently bought a 2005 yz450f. Bike runs great. Starts first kick every time. Here is the issue I'm having. I can start the bike after a couple days and it starts one kick. I can ride it and shut it off and it will start first kick. But if I stall the bike it will not start. I've kicked it for 10+ minutes. Gas off, gas on, choke, doesn't matter. Only way to get it running after a stall is to pull start it. I'm lost with this one.
