Guys, YZF426 that sounds like it overheated. Re-filled with coolant but when trying to start it notice coolant on top of the crankcase. Looked like it dripped from the exhaust. Pulled the exhaust and it had a lot of coolant. Can someone tell me if this motor tends to burn a headgasket before doing damage to other parts? Haven't torn it down yet. Any tips on what to look for? Thanks for any help. Lou.
