1975 Honda CB750F · Electrical tools Buying guide

Access and storage checks

The tuck-away wrench combines a thin-wall socket for deep CB plug wells with a handle that stores inside the socket. Check the fitted plugs and the available access before choosing it for a modified engine or ignition arrangement.

Reach into the plug wells

The source describes the thin-wall design for the deep plug holes on the listed Honda CB engines. Check clearance around the fitted plug and head before relying on the model listing alone.

Pack-away design

The handle tucks into the socket. The published overall length is 160mm; the description does not establish a fit inside the original 1975 CB750F tool compartment.

Plug wrench questions

Does 18mm describe the spark-plug thread?

No. It describes the plug’s hex, which the wrench engages. It is not a spark-plug thread specification, so do not use the wrench size to select replacement plugs.

Can the tuck-away handle set an exact tightening torque?

No. The handle is not calibrated. Start the plug by hand and use the applicable Honda or plug-maker torque specification with a suitable torque wrench when exact torque is required.
