Keihin Main Jet.
This is a Keihin main jet as used in various Keihin, Mikuni and Teikei carburetors.
For the physical dimensions, please see the photograph (sizes indicated in millimeters).
These jets are available from our stock in the following size:
Other sizes might be available on request.
Should you require other sizes than that are listed here, please contact us through our Contact Page.
The size, or calibration if you want to call it that, is engraved into the jet itself.
That way, you can always determine "what it was when it was produced".
In order to purchase the correct size for your carburettor, you need to make a choice through the drop down menu just above the "Add to cart" button.
Please note that the variety of Keihin jets is really overwhelming and that it is very well possible that your carburetor uses a different type of jet.
For this reason, we have created the Keihin Motorcycle Jets page.
Please visit this page to find the Keihin jet that you're looking for.
Other Japanese carburetor jets can be found on the Teikei and Mikuni pages.
These are Carburetor City jets of outstanding Japanese manufacture.
