2004 400ex.
ENGINE = STOCK and never opened up.
Haven't done any fuel/intake/engine mods for at least the past ten hours of riding.
Today i'm out putting around just in the yard since i have no skidplate and it's running just fine. Put it away, and then get it back out an hour later, and it won't rev past 1/3 of the way and it won't take any more than 1/3 gas or it just dies. There's no oil leaking out of the top end, and it runs okay as long as i'm super soft on the throttle and in the low rpm's.
It doesn't LOOK like i blew a head gasket.
Any input guys? I know my way around an atv, but inside the engine is something i'm new to.
