well i blew my motor a couple of days ago and so i finally went out today and tore the motor down and found that the stock piston sleave everything was still in there! that mean that the piston, rings, valeves, etc. is alomst 16 years old!! i just kinda thought that was cool. ive never heard of a quad this old haveing everything stock like this in the motor, but alas it all must go. im putting a 292 kit in there from Profab soon.
