Genuine Mikuni Pilot Jet
30 mm and larger UFO installation requires that you reduce your pilot jet by approximately 1/2 (or 1/2 plus 1) of the size you were using prior to UFO installation. These small pilots are usually not available at your local dealer. List the size you want in the special instruction area during the checkout process. Pilot jets come in increments of 2.5 (15, 17.5, 20, 22.5 etc…).
