Inspect the Cylinder Head and Timing Parts
First, check the valve guides, seats, and cylinder-head surfaces for wear or damage. Next, inspect the timing chain and tensioner. This kit does not list timing parts or valve-stem seals among its supplied components.
Compare the Master Tech Top End Option
If the repair also requires a timing chain, tensioner, and valve-stem seals, compare the Polaris Ranger and Sportsman 500 Master Tech Top End Rebuild Kit for 1996–2004 models. That package includes additional timing and cylinder-head parts.
