Frequently Asked Questions

What is an emulsion tube and why do I need it?

The emulsion tube meters fuel and air inside the carburetor for proper fuel mixture. If your carb is running lean or rich, a worn emulsion tube may be the culprit.

Is this a genuine Cycle Pro part or a reproduction?

This is a quality reproduction of the original Keihin part, designed to match OEM specifications.

How do I know if my carb uses an MKJ4 nozzle?

The MKJ4 is used in Keihin carbs on many V-twin bikes. Verify your carb model and part number before ordering to ensure compatibility.

Is this a direct bolt-on replacement?

Yes — if your carb originally used an MKJ4 nozzle, this part installs in the same location without modification.
