These references identify original Honda components, not Biker Bling product codes. Year-specific alternatives are not extra kit contents or proof of an official supersession. Match the original part and mounting position before fitting.

Model-specific aftermarket replacements: Biker Bling selects the supplied replacements for the original carburettor top-cover and float-bowl fixing positions. The cross-reference does not establish suitability for unrelated mounting points.

Materials and head style: The supplied bolts are A2 (304) stainless steel. Their head appearance may differ from the originals.

When should you replace these fixings?

• Rounded bolt heads: Worn recesses can complicate carburettor servicing.
• Corrosion or damaged threads: Inspect the cover and bowl threads before reassembly.
• Cover removal: Check the fixings whenever the carburettors are serviced.

New bolts cannot repair a warped float bowl, damaged diaphragm, failed gasket or fuel leak caused by another component.

Fitting information

• Work with the engine cool in a well-ventilated area away from ignition sources. Follow Honda’s fuel handling and carburettor service procedure.
• Keep dirt and fitting compounds out of the carburettors. Seat covers, diaphragms and float-bowl seals correctly.
• Start the correct bolts by hand and follow the specified tightening procedure. Do not use the bolts to pull a distorted cover into place.
• Check for fuel leaks and correct throttle operation before use. Have leaks or uncertain carburettor assembly checked by a qualified technician.

Customer questions

Are jets or adjustment bolts included?

No. This kit covers external top-cover and float-bowl fasteners only.

Do I need to disturb the carburettor adjustments?

Follow Honda’s procedure for the work being performed. Replacing cover bolts is not an instruction to alter mixture or synchronisation settings.
