When checking and re-gapping the valve clearances for the first time on this recent acquisition of an 82 1100i, noticed a thin dark brownish film/sludge in the lower sections of both left and right valve areas. The upper/intake areas were nice and clean, but the bottoms--not.
What would this accumulation suggest? It rubs off with a rag, minimal effort.
Thanks!
