1973 Honda SL350K3 · Piston Kits Buying guide

Match the piston package to the measured bore

The kit is described as standard size, with no numerical diameter in the product body. It includes rings, a pin and clips for the supplied piston rather than a separate ring-only set.

Parts to consider

Piston Kit with Piston Rings and Pin ~ Standard Size (07-0185) Standard-size piston kitOne piston with rings, pin and clips; two kits supply the stated contents for two piston positions.View part

Resolve the size before checkout

Standard size is a product description, not a measurement of your engine. Previous boring or cylinder wear may change the piston required. Obtain the kit’s actual diameter and have the repairer compare it with the measured cylinders and the applicable service specifications before ordering.

Use the contents to calculate the order

One package supplies one piston, rings, pin and clips; replacing both pistons requires two kits. The piston reference is 13101-312-010, with rings 13011-391-004, pin 13111-KR9-000 and clips 94601-15000. Use these for identification alongside the measured-bore check.

Buying questions

Can I choose standard size from the engine number alone?

The engine number helps identify the application but does not record later machining. Have the cylinders measured and confirm the kit’s diameter before selecting it for an engine whose repair history is uncertain.

Does one package include rings for both pistons?

No. The stated contents serve one piston position: one piston with rings, pin and clips. Replacing both pistons requires two correctly sized kits, after the requirements of the two bores have been confirmed.

Can I buy this as a ring-only repair?

This product also includes a replacement piston, pin and clips. If you intend to retain the existing pistons, have their condition and ring requirements checked before deciding whether this combined kit is appropriate.
