1981 Honda CB900F Instrument Mounting Nuts

This 1981 CB900F instrument-hardware route contains a four-piece cap-nut set for stock-type speedometer and tachometer mounting. Match the existing nuts and reference before ordering. A changed gauge bracket may need different hardware, so the original-model application should not be extended to every custom cockpit.

1981 Honda CB900F Supersport · Instrument Mounting Nuts Buying guide

Check the stock instrument mounting hardware

The package contains four cap nuts replacing reference 94021-06020. It is a focused hardware choice for the original-style instrument mounts rather than a broad collection of brackets, cushions and fasteners.

Match the original-style application

The source identifies stock OEM-type speedometer and tachometer mounts. Inspect the existing mounting studs and nuts before choosing the set. That application is useful when maintaining the original arrangement, but does not verify the thread or engagement on an aftermarket instrument bracket.

Keep other mounting needs separate

Inspect brackets, mounting studs and cushioning pieces while access is available. The four-nut set repairs only its fastener positions. Honda also warns against leaving original instruments upside down during service because internal oil can reach the lens.

Buying questions

Why do the instruments still move after the cap nuts are tightened?

Check the mounting studs, brackets and cushioning pieces for wear or damage. More tightening cannot repair a broken support or deteriorated cushion and may damage the mount. Locate the movement before ordering more fasteners.

Can these cap nuts be used on custom gauge brackets?

Match the custom bracket’s thread, engagement and clearance requirements first. The set is listed for stock-type instrument mounting. Its Honda replacement reference does not establish fit on an aftermarket stud or bracket.

How should I protect the original gauges while servicing their mounts?

Support the cluster without straining its cables or wiring and follow the F removal procedure. Keep the original instruments upright when set aside; Honda warns that leaving them upside down can allow internal oil onto the lens.
