This complete kit includes intake exhaust valves and matched valve collets (valve keepers), premium aftermarket engine spare parts specially designed for CG200 200cc four-stroke air-cooled motorcycles, widely used for commuter bikes, dirt bikes and ATVs.

The intake and exhaust valves are forged from premium heat-resistant alloy steel. Through precision machining and valve stem grinding treatment, the valves maintain stable performance under continuous high-temperature combustion environment. It resists thermal deformation and valve burning, ensures tight sealing on valve seat, maintains good engine compression and stable power output.

Valve collets are manufactured with high-strength carbon steel and quenching hardening process. With precise taper structure, the collets provide strong clamping force to lock the valve spring retainer firmly onto valve stem. It prevents valve falling off under high RPM operation, avoiding catastrophic engine damage caused by loose or broken original collets.

This kit solves common engine faults: burnt valves, insufficient compression, hard starting, power drop, abnormal valve noise, loose and broken valve collets. Manufactured strictly following OEM dimensional standard, all sizes perfectly match original components. Direct bolt-on installation without modification, ideal for top-end engine overhaul and regular maintenance.

Every valve and valve collet passes dimensional inspection and hardness test before packaging to guarantee reliable performance and extended service life. Cost-effective repair spare parts for motorcycle repair shops, DIY mechanics and wholesale distributors.
