i was running my bike kind of hard- nothing special. i get home, let it idle for 10 secs, shut it off and anitfreeze starts spilling out of the overflow tank. wtf? i talked to my friend and he says the thermostat might be stuck? i'm new to crotchrockets and i have no idea what is going on. i let it sit for half an hour and rode it around town again and it didn't overheat or anything. i have no idea. any thoughts would be greatly appreciated. thanks in advance.
