I bought a used 2006 raptor 700r had blown base gasket. Had coolent all in the motor. Rebuilt the water pump. Flushed it out with diesel a few times. It has a JE 11:1 high compression piston, after market cam, motorworks FMI , DMC comp duel exhaust. I replaced couple months ago with OEM base and head gasket... It already blown . 😳. Was running 91 zero octane gas. Also shooting out coolant out of radiator and over flow shooting out coolant. Has also new thermostat OEM.
