This year I "stole" a Harley, and brought it out of a 6 (maybe more) year slumber. Now that I have ridden it a few times, I started to pay attention to the little things. One thing in particular was burning oil.
The rear cylinder had (and still has) a subtle puf-puff that is visible in direct sunlight, nothing that concerns me. I can't however get over the cloud from the front cylinder, similar to what hangs over LA.Initially I blamed all on the valve seals, as the valves were nice and wet when looking through the exhaust ports. But since the piston soak cost me roughly 25cents, and coking of the rings makes sense (air cooled+long time sitting) I went for it. Put ATF and gasoline into the cylinder for a day or two, disconnected the plugs, cranked over with plugs out, then in, then started her up. When the oil started burning off, I shut her down and did another 2 day soak. Now both pipes smoke equally little.
At the moment I dumped a 1/4cup(roughly) of the atf/M1/PP/techron/gasoline mix (just because that was on hand) into each cylinder after warming up the engine slightly until tomorrow. I am sure the results will not improve, but hey for a few cents why not try?
