Stainless Steel Carburettor Cover and Float Bowl Bolt kit for CBR400R NC23

Replacement stainless steel carburettor bolts for the top covers and lower float bowls on Honda CBR400R NC23 1986–1987. The kit covers those fixing positions across the original four-carburettor bank. It does not replace jets, mixture adjustments or carburettor rack mounting hardware.

What you receive

• Stainless steel carburettor top-cover bolts.
• Stainless steel lower float-bowl bolts.
• 1x Biker Bling anti-seize compound pack (7 g).

Scope: The table identifies the carburettors covered, not an individual bolt count. Covers, float bowls, gaskets, diaphragms, jets and complete carburettors are not included.

Important fitment notes

• Compatibility: For Honda CBR400R NC23 1986–1987 with the original component arrangement described above. Check aftermarket or modified components before ordering.
• Aftermarket parts: These are aftermarket replacements, not genuine Honda-branded components.
• Product photographs: Generic photographs illustrate the supplied style. Use the contents list for this kit’s scope.

Original Honda part references

• 93500-04010-0A – original carburettor cover / bowl fixing listed in the Honda catalogue.
• 93500-04012-0A – original carburettor cover / bowl fixing listed at alternate positions.

These Honda references identify the original mounting components. The supplied parts are aftermarket replacements, not genuine Honda parts. Match the correct fixing to its original position; alternative year references do not mean additional bolts are supplied.

Supplied bolt material: A2 (304) stainless steel. The material grade alone does not establish mechanical-strength equivalence to Honda’s original hardware.

When should you replace these fixings?

• Rounded cover or bowl bolt heads: Damaged recesses can make carburettor servicing difficult.
• Corrosion or damaged threads: Inspect the bolts and cast mounting threads before reassembly.
• Carburettor maintenance: Check the cover seating, bowl gasket and fixing positions when these components are removed.

Fitting information

• Keep dirt and fitting compounds out of the carburettor. Protect the diaphragms and seat the covers and float-bowl seals correctly.
• Match each bolt to its original position and start it by hand. Follow Honda’s tightening instructions and use compounds only where permitted.
• Check for fuel leaks and correct operation after assembly. New bolts cannot repair a damaged bowl, diaphragm, gasket or stripped casting thread.

For general background, read our stainless steel motorcycle bolt fitting guide. Honda’s workshop procedure takes precedence.
