Sportsman 700 knocks

Noisy engine to begin with because of the hydraulic lifters and push rods. A deep knocking noise cold be more serious such as a piston, lower rod bearing or crank bearing. Sound can radiate through out the engine. A good engine stethoscope can help narrow down where the noise is coming from.

Starter bendixes are pretty strong on the 700/800 engines,a lot stronger than the ones on the 500,ect. Plus the bendix should kick back once started. Just pull the cover and check it out and see if it spins out and retracts back ok. Could still be a rod bearing or crank bearing transferring noise through the engine case.

Yes it will only come out so far and hit the flywheel by hand. Even if you turn the flywheel and the bendix retracts back,sounds like it's working ok.Behind the stator and flywheel and cover are the crank sprocket,cam and counter balancer sprocket along with the oil pump sprocket.If they are ok,the clutch has been eliminated as the knocking noise also,then still could be a rod or crank bearing.700s were sort of noted for that happening.
