James Dean designed the JDJetting kits so that you don’t have to be an expert to get professional high performance results!! Even better, technical support is provided.
The James Dean custom jetting kit is designed to improve throttle response throughout the 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
