Frequently Asked Questions

What is included with SOHC CB750 oil-tank cap 55105-300-010?

One chrome oil-tank cap with dipstick and sealing gasket is included, replacing Honda OEM 55105-300-010.

Is this cap for the fuel tank or engine crankcase?

No. It fits the separate dry-sump oil tank on the listed 1969-1976 CB750K models.

How should the SOHC CB750 oil level be checked?

Follow the Honda dry-sump oil-level procedure for engine temperature, motorcycle position and dipstick use. Checking after the motorcycle has sat can give a misleading reading if oil has migrated from the tank.
