The Mikuni carburetor with the identification number 13886A is a Mikuni VM38-86 carburetor. The “VM” designation indicates that it is a round-slide type carburetor, and the numbers “38-86” specify the size of the carburetor in millimeters, with a 38mm bore diameter.


Installing this carburetor on a Husaberg is not a common modification, as the stock Dellorto performs adequately. Consequently, finding someone with experience and baseline jetting specifications may be challenging.


If it starts well, doesn't backfire on deceleration, or stumble upon rapid throttle opening, it is likely jetted reasonably well. The needle affects throttle response from 1/4 to 3/4, so experimenting with different needles could be beneficial. Sudco offers a wide range of Mikuni parts on their website: Sudco Intl. Corp. - Carburetors. A quick-pull throttle might have been installed, or this carburetor's slide could open faster than the stock carb, making the power delivery feel like an all-or-nothing response.
