This is obviously an old bike and I have had this leak since I bought the bike last December. The oil leak starts only when the engine is really hot and it is *tiny* and is seen where the pulse generator output cable is on the left crankcase cover. I figured this was due to an old gasket, so I replaced it with an original Honda gasket. I also used a torque wrench to tighten the bolts nicely if it means anything at all. Anyway, the leak has not gone away. Mind you it is tiny, but I would like to get rid of it if at all possible. But how? P.S. I applied a tiny layer of grease on the gasket before installing it so it makes nice contact. And, the factory gasket came with a nice dab of sealant all around it. I have researched high and low but come up empty with new ideas.
