I just bought a 95 Sportsman 400 4x4, one owner little old man, very well maintained, it sat for two years, I got it fired up, did some maintenance on it, rode it for around three miles, everything worked great. Came out the next day and there was around a three inch round 2 cycle oil puddle under the quad. I see no leaks anywhere near the injector pump or oil tank. The oil is dripping from behind the motor, behind the clutch assembly. Anyone have any idea where this is coming from??? The injector pump is at the front of the motor.
