Okay I have not gone to look at the bike yet. Just tossing around a few things. My good friend says he's is getting oil into his coolant and could see it rainbow on top and oil filming on the cap. He says that there is no coolant getting into his oil. I plan to go about compression and leak down for a possible head gasket issue and double check his symptoms. Also has anybody had oil get into their coolant via water pump oil seals? Or have this problem?
