Part: Honda CB350 (CL350 Scrambler / SL350) & CB360 (CL360 Scrambler / CJ360) Intake & Exhaust Valve Kit
Why You Need This: A proper top end overhaul not only involves refreshing the cylinders but going through the cylinder head and inspecting the valves, valve guides and the the whole valve train. Intake and exhaust valves do wear out with high mileage and should be replaced if they measure out of service limit or measure out of concentric alignment.
Since original OEM Honda replacements are all but obsolete, Common Motor has stepped up the game once again and manufactured our own brand of super high quality engine valves for the CB350 (CL350 Scrambler / SL350) & CB360 (CL360 Scrambler / CJ360) families of bikes. We have worked diligently with one of the top OEM engine valve manufactures in the world to fabricate brand new engine valves using modern materials designed to out perform the originals.
- Manufactured from Japanese made JIS standard SUH35 steel
- Valves are Tufftride coated
- Extra wide valve face to accommodate variations in worn valve seats (easier to lap)
- Stellite #1 coated (50-58 HRC) on the tip of the valves (extra hard for the tapping of the rocker arm tips) to prevent "mushrooming"
Sold as a kit of four, with two intake and two exhaust valves. While you are replacing the valves it is also a good idea to measure the valve guides and replace if out of specification. Put it all back together with a fresh set of overhaul gaskets, intake and exhaust valve guides.
Installation Tip: Valve seats need to inspected and touched up from a 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 / wear. Guides will need replacement before attempting to cut or lap valve seats. Honda CL360 / CJ360 / CB360 models use valve stem seals, that should be changed when the valves are replaced if you are still using the factory style iron valve guides.
