I have a very small oil leak which appears to be coming from the side of the left cylinder just under the head gasket. After a 30mi ride all that appears is a sheen of oil on the fins. I haven't even seen a noticeable effect on the oil dip stick but there's no doubt that the oil is there ( the oil is clean with no appearance of carbon contamination). I have had the tank off several times to examine the entire top end and have not seen any apparent leak other then near the head gasket. Could this oil be coming from the head gasket? I did have the head and cylinders off 9 months ago to install a heli coil in the left cylinder and while I was there, put a new set of rings in and a pair of Mikuni VM 34 mm round slide carbs. If it was a head gasket leak, surely I would hear it? The left spark plug indicates a slightly rich mixture. The bike runs great.
As always, thanks for any help.
