1968 Honda CB350K0 · Tappet Caps & Engine Covers Buying guide

Choose a cap for its fit and finish

The featured replacement is an individual aftermarket tappet cap supplied with a gasket. Its finned chrome appearance should be considered alongside the original-style finish you want for the engine.

Parts to consider

Order by the caps being replaced

The tappet cap is sold individually with a new gasket included. Count the caps needed for your particular repair instead of treating a single purchase as a complete engine set. Inspect the sealing surfaces while assessing which pieces require attention.

Check the actual cylinder head

Older twins often arrive with previous repairs or replacement top-end parts. Compare the fitted cap’s threads, shape and seating arrangement before ordering. The finned chrome design is aftermarket, so choose it deliberately where visual originality is part of the restoration plan.

Common buying questions

Is the gasket included with each tappet cap?

Yes. Each individually sold cap includes a gasket. Account for that supplied seal before adding separate sealing parts to the order for the same cap replacement.

Is this the original plain-finish Honda cap?

It is an aftermarket finned chrome-plated cap. Choose it for that appearance, and compare it with the engine’s existing finish if you are trying to preserve an original-looking restoration.

What if the cylinder head has been replaced?

Match the actual cap thread and sealing seat with the replacement reference, rather than relying solely on the frame year. A changed head can affect which cover parts you need.

Not sure which part you need?

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