Frequently Asked Questions

What is included with Honda primary-chain set 23131-300-315?

Two genuine Honda primary chains, OEM 23131-300-315, are included—the complete primary-chain set for one 1969-1978 SOHC CB750 engine.

Is Honda 23131-300-315 a cam-chain set?

No. These are the two primary chains that transfer engine power to the clutch; the cam chain is a separate engine-timing component.

What should be inspected when replacing the SOHC CB750 primary chains?

Inspect the primary-chain tensioner, guides, sprockets, clutch components and related bearings for wear. Follow the Honda service procedure for engine disassembly and reassembly.
