I have a 2006 yz450f and everytime i go for a ride as soon as i stop there is some coolant that come out the overflow. i know it could be my head gasket but the bike doesn't even smoke white or anything. it also gets really hot really fast. im thinking it could be the cap or the head gasket. any help would be appreciated.

I'd start with a leak down test, pressurize it with shop air take off the rad cap and look for bubbles, get a OTC leak down tester they are cheap and will come in handy again. How many hours are on the bike?
