Cannondaleriders

Two out of the last twelve times I went to ride my quad (after it had sat for a min of 4 days) the engine seemed to crank real hard and did not want to turn over. It seemed as though the engine was liquid locked or the battery was just about out of juice. Once the engine finally started (after a few spits coughs and sputters) there was quite a bit of white smoke pouring from the exhaust. Once running the engine sounded normal both times. The case oil was visible (half way up the site window) and everything else was normal. This quad has no more the 35 hours on it and I have done all the up dates that I know of, Stage 8 kit installed, updated the motor mount, vent hose, valve cover, battery trey, and I run evens coolant now???????????????. Am I missing anything? Some say I am anal about my maintenance. I wash the bike and clean the air filter after every ride and change the oil after every other ride. I use Golden Spectra 20W50 in the engine and 80W in the case. Do you think I have to much oil in this thing? Or could it be the engine oil check valve? I was told by another rider that there is a check valve in the spar or just inside the engine that shuts of oil to the motor when it is not running. And if that check valve is not working rite oil will flood the engine and eventually get around the rings and into the cylinder, especially if it sits for to long, which will cause the engine to spoke like a chimney. I just want this thing to last and the smoke worries me???????????????BIG TIME? Any help you can offer up would be great? Any thoughts??

Thanks in advance!!

The smoke is white? Check your coolant level. Burning oil gives off a dark gray/black smoke. Burning coolant gives off a white smoke.

The collant leve has not changed in 3 months. I don't think that is the problem. Or I hope not!! Any other ideas?
