My engine is in great shape and passes a compression check with flying colors. The valves have always been in proper clearance adjustment.
I use Mobile 1, motorcycle synthetic 10/40 oil. The oil level is never over the full mark and I do not have a problem of oil leaking on the head or out of the breather tube or speedometer cable!
I drive at HIGH ALTITUDE (5000 ft to 9000 ft).
