I have a raptor 660 2002 i just purchased. I am new to the sport and have very limited knowledge! on my first ride this weekend i rode for about an hour. i noticed that oil was being blown for the crankcase breather tube so i rode back over to the truck turned off the quad and now it wont even start. I checked the oil and it has plenty and i have good compression and good spark. That is all i know any advice will help please.
