Frequently Asked Questions

How many float-bowl gaskets are included and required?

One O-ring-style float-bowl gasket is included. Every listed CB550, CB650 and CB750 application uses four carburetors, so four gaskets are required to reseal the complete rack.

Is float-bowl gasket 20-8030 a complete carburetor rebuild kit?

No. It seals one carburetor bowl; float valves, jets, needles and other seals are separate service parts.

What should be checked before installing a float-bowl gasket?

Clean the sealing groove and bowl flange, check the bowl for distortion or corrosion and make sure the new O-ring remains seated while the bowl is tightened evenly.
