Frequently Asked Questions

How many +0.50 mm CB750 pistons are included, and what comes with each kit?

One Japanese-made second-oversize piston, one piston pin, and two pin clips are included. A four-cylinder 1969-1976 Honda CB750K needs four kits to replace all four pistons.

Are piston rings included with the +0.50 mm CB750 piston kit?

No. Piston rings are sold separately; matching +0.50 mm ring set SKU 05-7002 services one piston, so four ring sets are needed with four piston kits for a complete engine.

What does Honda OEM 13103-300-030 second oversize require?

The piston replacing Honda OEM 13103-300-030 is 0.50 mm over standard. Each cylinder must be measured, bored, and honed for the actual piston with the clearances specified in the Honda service manual.
