Product Overview
Low compression, oil burning, a damaged cam lobe, top-end noise, or cylinder scoring can turn a running issue into a rebuild decision. This kit groups the major cylinder-head-side wear parts so a compatible Polaris 500 engine can be repaired without sourcing each item separately.
A complete teardown and measurement still comes first. Polaris 500 cylinders use early and late cam-chain-opening designs, and engine history may reveal crank, rod, oiling, or head damage beyond this kit. Compare the original numbers, 92 mm bore, cam-chain opening, piston design, and every included part before assembly.
Key Features & Performance
- Standard 92 mm cylinder and piston package
- Includes piston rings, wrist pin, and circlips
- Includes camshaft, three rocker arms, and chain-tensioner parts
- Gasket set supports top-end reassembly
- Broad compatible Polaris 500 application when the engine version is matched

Frequently Asked Questions
Q: Is this a complete bottom-end rebuild kit? A: No. It is a top-end-focused kit; inspect the crankshaft, rod, bearings, and cases separately.
Q: Why does the cam-chain opening matter? A: Polaris used different cylinder castings, and the opening size must match the engine.
Q: Will this fix low compression automatically? A: Only if the cause is in the supplied top-end parts and the head, valves, lower end, timing, and oiling system are serviceable.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
