Keihin factory rebrand carburetor for all years Kayo Bull and Predator 125. Has #35 Pilot Jet N424-74C style and #88 Main Jet 99101-116 Style. These are the Keihin jet scale. Requires a 38mm / 39mm air filter or stock air box. You will need to reuse your old throttle cap with this new carb to clear the gas tank. Do not reuse the slide and needle from your old carb. Choke lever is tough to reach on the Bull 125 because you are not using the cable choke anymore.
Put this new carb on to replace the original one that was nothing but problems. The ATV started right up after sitting all winter on the first try. This new carb seems to be a great improvement over the original.
