I know its kind of late to be discussing this but for the past 4 or 5 years my quad has been knocking and leaking oil… I cannot see where the oil is leaking from but about 5 minutes after starting it I start smelling burnt oil. I check the oil before each ride and it is always at the full line…now about the knocking it is like a clicking/knocking what could cause this…I hope I didn’t wait to long for it to be something very serious. I use it in the winter plowing for the most part and rid it a few times in the summer just to start it and run it. Someone told me it could be the spark plug is to long but its the exact same as the original.. Please help me out..
