Frequently Asked Questions

How many exhaust valves are included and required for the compatible Honda twins?

One exhaust valve replacing Honda OEM 14721-292-010 is included. The listed CB450, CL450 and CB500T parallel-twin engines use two exhaust valves, so two are required to replace every exhaust valve.

Can a new exhaust valve be installed without checking the valve seat and guide?

No. Measure guide clearance and inspect or machine the seat for correct contact and sealing. Check installed height, spring condition and valve clearance during assembly.

Can the exhaust valve be substituted for intake valve 14711-292-000?

No. Intake and exhaust valves are application-specific and differ in operating conditions and dimensions. Match Honda OEM 14721-292-010 for the exhaust position.
