I just acquired a 1995 Vulcan 750. the bike was sitting for years. i cleaned the carbs and got the bike started. The bike will run but after 60 seconds coolant and oil comes flowing out into the air filters. i removed the air filter and can see the foamy frothy oil/coolant coming out of the overflow. i don't want to start taking the bike apart yet. thought i would try this site first. if anyone else came across this problem. I think it is either the head gasket or something internal. not sure thanks for any help. i can restart the bike and same issue.
