JD Jetting jet kit JDS001.

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.

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

This fits: the 2000-2007 Suzuki DR-Z400E (that’s the one with the slant Keihin FCR39 flatslide carburetor).
