1974 Honda CB750K · Pistons & Rings Buying guide

Match piston and ring sizes to measured cylinders

A cylinder’s condition and any previous rebore determine which size is suitable. Agree the repair size with the person inspecting or machining the engine before selecting pistons, rings and associated parts.

Let inspection determine the rebuild size

A previous owner may have rebored the cylinders or fitted different pistons. Have the bores and pistons assessed against the service limits, and agree any machining requirements before purchase. Standard, first-oversize and second-oversize listings describe different dimensions; the motorcycle’s year alone cannot select among them.

Count the parts for each cylinder

The featured standard piston kit contains one piston, its pin and two clips, with rings sold separately. The standard ring set also serves one piston. Build your order around the cylinders being repaired, checking each chosen listing because other kits may include different combinations of parts.

Common questions

How many standard piston kits are needed for all four cylinders?

The featured standard kit serves one cylinder, so its listing specifies four kits for a complete four-cylinder rebuild. It excludes piston rings. Confirm the contents of the exact kit you choose, as other packages may differ.

Can I use oversize rings with standard-size pistons?

Choose rings to match the piston and the bore dimensions specified for the repair. Do not use an oversize label as a shortcut for correcting wear. Ask the engine rebuilder to confirm the required combination before ordering.

Do I need an extra pin-clip pack with the standard piston kit?

The featured standard kit already includes two piston-pin clips along with the piston and pin. Rings are separate. Add the separate two-clip pack only if your chosen package or repair needs additional clips.

Not sure which part you need?

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