Intake and exhaust valves for Honda CB175 and CB200 twin motorcycles.
Note: Sold as a set of Four — two intake valves and two exhaust valves.
No top end rebuild is complete without a fresh set of valves. If you're rebuilding the cylinder head of a Honda CB175 / CL175 Scrambler / SL175 / CB200 / CL200 Scrambler, Common Motor offers these high-quality intake and exhaust valves to replace your worn out OEM valves.
Our Common Motor Collective "Airlock" valves are better than the OEM part, engineered and produced by CMC specifically for use in vintage Honda 175 and 200-series twins. To produce these valves, we worked closely with one of the top OEM engine valve manufacturers in the world to fabricate them using modern materials designed to outperform the originals.
While replacing the valves, make sure to measure the valve guides and replace them if they're out of spec. While the head's off the engine, refresh everything with a set of new gaskets for your CB175 or CB200.
Valve seats need to be inspected and touched up by a qualified machine shop if heavily pitted. Otherwise, you need to lap with the new valves to the old seats. Guides must be measured for excessive play or wear. Guides will need replacement before attempting to cut or lap valve seats. Honda 175 and 200-series twins use valve stem seals that should be changed when the valves are replaced if you are still using the factory-style iron valve guides.
