JD Jetting jet kit JDKH41.

James Dean designed the JDJetting kits so that you don’t have to be an expert to get professional high performance results. The James Dean custom jetting kit is designed to improve throttle response throughout the rpm range by using specially made multi-taper needles. These are based on the most popular settings used by new generation MX and off-road riders around the globe and the results are impressive. Exceeds the performance of other standard factory jetting.

This kit was specifically designed for the Keihin PWK38 AirStriker carburetor (w/ screw top).

You will get: 2 multi-taper needles, 1 needle clip, 4 main jets and 1 pilot jet. Also included is a manual which shows you what set up to use.

This fits: the screw-top Keihin PWK38 AirStriker carburetor (see 3rd image) (carburetor not included). This carburetor is used in a wide range of 125-500cc. 2-stroke engines.
