1979 Honda CB750L Limited · Engine Parts Buying guide

Build a Limited engine service order

The Limited catalog includes DOHC gasket sets, individual valve shims and oil-service parts. Start with the assembly you are opening, then separate service consumables from internal engine components.

Parts to consider

Honda CB Oil Filter ~ Replaces 15410-426-010 Paper oil filterStock-type paper element; housing O-rings, spring and washers are separate.View part 1979-83 Honda CB750 DOHC Athena Overhaul Gasket Set Athena overhaul gasket setIncludes cover and top-end gaskets, 16 valve seals and four cylinder-sleeve O-rings.View part Honda CB1100 / CB1000 / CB900 / CB750 Valve Shim Kit Valve shim assortmentTwenty 25mm-diameter shims in ten specified sizes, with a plastic case.View part

Choose the scope first

A cover leak does not automatically call for an overhaul set. Individual alternator, clutch and valve-cover gaskets are available for the Limited. For deeper work, compare the overhaul contents against your dismantling plan; a gasket assortment does not replace an inspection of shafts, bores or valve gear.

Measure before buying internal parts

Ring sizes and valve-shim thicknesses are service choices, not preferences. Record the existing components and measurements using the appropriate Honda service manual. Keep cam chains, the internal primary chain and rear-wheel drive parts separate when preparing an order.

Buying questions

Does the oil filter include the housing hardware?

The paper filter is supplied separately from the housing O-rings, spring and washers. Check those pieces before ordering so the filter service does not stop for missing hardware.

Is the valve-shim kit a complete adjustment for my engine?

It is an assortment of twenty shims in ten sizes. Your measured clearances determine the thickness and number needed; some engines may need individual sizes beyond that assortment.

Can I order engine parts from another CB750 variant?

Use the explicit 1979 CB750L application and the installed component. Shared DOHC listings can be useful, but a similar year or engine size does not establish every gasket, seal or drivetrain choice.

Not sure which part you need?

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