Been searching old threads and find many closed on this issue, but not exactly what I am seeing. On the front cylinder, I am getting oil that puddling and flowing over to spark plug side of the motor. On a hot day, pushing the bike hard, I get a puddle of oil around the spark plug. Lots of oil spray on the air cleaner and exhaust too. I think it is coming from the top O-ring on the push rod? Would that be right? I don't know which push rod though. Does this mean that I have to change the o-rings? I have stock push rods and 33,000 miles on a '98 EVO. Probably a good time to swap over to EZ Adjust push rods, eh? Thanks for the help.
