I have a small oil leak. I cant see exactly where it is comming from, but a few drops collect on the top of the top rear fin of the left rear jug - this is right above the ignition key. I dont know if this could be a head gasket or not? It is strange, because it takes a while for it to form. For example, I road for 7 hours on the Fourth of July. No leakage. I parked the bike in my garage and watched it. I did not see any oil until a few days later. I know that this is not a lot of information, but any ideas?
