I've got a very small oil leak from top of front cylinder on left side. No puddle under the bike, just a thin film of oil on the front left side of the cylinder facing the front of the bike. I'm assuming its the valve cover gasket that's leaking. Doesn't seem to be affecting the oil level, and bike is otherwise running fine. A while back I put in DLP's PAIR valve block-off plates to deal with the popping on decel...anyone else with those plates in develop a leak afterwards? Not sure if one could have anything to do with the other...rear cylinder seems fine and leak free. Any ideas? Thanks guys.
