1973 Honda CB350G Intake & Exhaust Valves

The CB350G twin has separate intake and exhaust valve choices. Order for the position being repaired, then have the cylinder-head condition assessed so that a new valve is not fitted into an unresolved guide or seat problem. Intake valves are sold individually.

1973 Honda CB350G · Intake & Exhaust Valves Buying guide

Match the valve to its cylinder-head position

An intake valve and an exhaust valve are distinct service parts. Let inspection determine which positions require replacement, and prepare the head work alongside the parts order rather than choosing by appearance alone.

Plan the head work with the parts

Replacement valves are only one part of a cylinder-head repair. The condition of the guides, seats and associated hardware determines the work required. Agree the repair plan with the machinist before ordering valves for positions that may not need them.

Keep adjustment and replacement separate

The twin uses eccentric rocker-arm pins for valve adjustment. A replacement valve is not an adjustment part, and CB750-style tappet-screw assumptions do not apply. Use the Honda twin service procedure for checks after the head is reassembled.

Buying questions

What should I check if the cylinder head has been replaced?

Identify the fitted head and compare the removed valve with the correct intake or exhaust replacement. A CB350G frame does not establish the application of a different engine or cylinder head.

Is the intake valve sold as a pair?

The intake valve is sold individually. Base the order on the positions your head inspection identifies, rather than assuming the price covers both cylinders.

Should I buy valves before the head is inspected?

Inspection first is preferable. Guide and seat condition can affect the repair plan, so confirm which valves need replacement and what machining is required before ordering.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
