Factory Pro Carburetor Jet Kit
Easy to install and tune - no slide drilling! Adds more low-end / midrange, if the proper main jet is selected, more top-end power.
Most Kaws tune well and easily with the Factory Pro kits - however, some Kaws have a problem with low speed operation -If that's the case, and you've adjusted and reset the float height leaner and 18mm still isn't lean enough at cruise, and especially if the problem is on 1, 2 or 3 cylinders, please inspect the float valves for the dreaded rubber tip shrinkage. Some fuel additives attack the float valve rubber tip and cause it to shrink and distort. Now, nobody needs a shrunken, distorted rubber and, being non-round, will allow not shut off fuel in the carbs with the bad float valves and cause very rough low speed running (as the fuel level keeps rising in the carb bowl). It's not a "common problem", but if the normal tuning stuff doesn't work...........
