I have an 85 600 and was wondering if that engine leaked coolant into the engine at all. What happens when coolant gets in the the engine. Iam going to bore to a 650 pretty soon. Any pointers. Last winter I was riding and suddenly lost all my coolant in the engine or alot of it. and can't figure where it came from. I don't know if there is a crack some where in the cylinder or what.
