Coolant clean, no sign of coolant in the oil. Valves were adjusted and were pretty good before adjustment. Cams and that area clean, no gray sludge,no sign of coolant in the oil.The only smoke is when warming up, white smoke that is typical of both ofmy motorcycles andmy pickup. Moisture from the exhaust in the cold air (it's still cold here).
I'll run a compression test tomorrow, and try the oil/rings test.
Lapping the valves while the heads are in place....interesting. And how do you grab that valve stem without damaging it? A drill? Soundspotentially destructive. Then getting the lapping compound out of the cylinder....with compressed air?? Tell me about the details I am missing. I need enlightening.Iimagine lapping compound doing it's work on the rings for a few strokes before the engine fires up and burns up the compound.
I recall lapping valves in a small engine class decades ago, and applying only light pressure to the valve,minus the valve spring. If I can figure out that it's defintely valves, I feel saferremoving the head(s) and lapping the valve(s). My GL1100 is the mule for a sidecar rig. I've put 20k on it, mostly highway miles. Because of reduced gearing, the engine runs pretty high rpm's on the highway, 5000 to 6000 rpm.
As an edit; mileage on the engine is 45k. This is a replacement engine, which I bought with 20k on it. Cranking was even when I got it, although it's obvious this engine sat for a long time. I never checked the compression.
