I dropped a spare engine in my bike after a drastic failure....any idea why with everything put back together I am having a low oil pressure problem. With a cold engine the light comes on below 2k RPM. as the engine heats up the low pressure light only stays off with more RPMs....is this anoil pump problem or simply moisture and air in the crankcase ? I have run 16 quarts of oil through the engine. When I start the engine the oil in the window becmes cloudy. plus the bike holds 3.1 liters according to the specs... hwever it shows overfull after adding 2 quarts. any idea?
