My bike has developed an oil leak. I can’t tell if it’s the clutch case gasket or the head gasket. What is the more common gasket to go out? It is only leaking on the left side, and I can’t tell if it’s splashing up on to the head gasket from the clutch cover , or if it is the head gasket. What would be a good test to check were the leak is coming from? The dealer wants $120 to determine where the leak is coming from. $300 if it’s the head gasket. If the leak is small should I live with it for a while longer? It only has 5k miles on it. Is it worth it to have the dealer find the leak and I do the head gasket for $120 or should I just let them do the work? I know I want to do the work my self, but I don’t know if I am ready to take out the head just yet. Thanks all any advice would be great.
