1973 Honda CB350G · Engine Buying guide

Plan the twin-cylinder repair by assembly

A top-end overhaul, a timing-drive refresh and a leaking shift shaft need different parts. Build a short list from the dismantled assembly rather than treating this category as a complete engine kit.

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 cover both cylinders when standard-size pistons suit the measured bores.View part Honda CB Cam Chain Guide Roller ~ Genuine Honda Brand ~ Replaces 14601-312-000 Genuine Honda guide rollerGenuine Honda cam-chain guide roller, listed for the 1973 CB350G twin.View part Honda CB Shift Shaft Seal ~ 14 x 28 x 7 ~ Replaces 91206-286-013 Shift-shaft oil sealJapanese-made shift-shaft seal measuring 14 × 28 × 7 mm.View part

Size the piston order after inspection

Each standard-size piston kit covers one piston and includes its rings, pin and clips. Two kits cover both cylinders, but only when standard size is appropriate. Have the bores assessed before buying; replacement parts do not correct an unsuitable or worn bore.

Keep each service system distinct

The cam chain drives the overhead camshaft; the rear drive-chain adjuster works at the rear wheel. The twin also uses a centrifugal oil filter. Match each small part to its actual assembly instead of transferring CB350 Four or CB750 service assumptions.

Buying questions

Does one piston kit rebuild the whole twin?

No. The kit covers one piston with rings, pin and clips. Buy two only if both cylinders need rebuilding and measured bore condition supports standard-size pistons.

What else should I inspect when replacing a cam-chain roller?

Inspect the guide, chain and supporting hardware as an assembly. A roller replacement does not establish that its pin, collar or the remaining timing-drive parts are serviceable; select additional parts from the inspection findings.

Should I order a seal before stripping the engine?

First identify the leak location. The featured seal is specifically a 14 × 28 × 7 mm shift-shaft seal; it is not a general-purpose engine seal kit.

Not sure which part you need?

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