1970 Honda CB750K · Electrical Tools Buying guide

Match the plug wrench and switch tool to the fitted parts

One tool matches an early switch nut arrangement; the other has a stated spark plug size, thin-wall design and overall length. Review those distinct details against the fitted component rather than selecting by the broad electrical category.

Check the switch that is actually present

The ignition nut tool application includes the CB750K 1969–76 switch. If the motorcycle has a custom or substituted switch, compare the retaining arrangement separately before choosing the tool. A familiar ignition location is not proof that a replacement switch uses the same nut or tool interface.

Allow working room for the socket

The offered wrench has a thin-wall socket and 160mm overall length. Compare the space around the fitted plug and above the engine before choosing it; the tuck-away handle is a storage feature.

Electrical Tools: buying questions

Does an 18mm plug wrench mean an 18mm plug thread?

No. The wrench size describes the hex it grips, not the thread entering the cylinder head. Check the installed plug’s hex size for tool selection; select the replacement plug by its own engine application.

What if the ignition switch has been replaced?

Compare the retaining nut and tool engagement with the early CB750K switch application. A custom switch housing may use a different retaining arrangement even when it occupies the original location.

Can the tuck-away wrench set exact spark-plug torque?

The handle is not a calibrated torque tool. The listing describes an 18mm thin-wall wrench with a compact tuck-away handle; use the correct plug or Honda tightening specification and suitable equipment when exact torque is required.
