The James Dean custom jetting kit is designed to improve throttle response throughout the range by
using specially made multi-taper needles. These are more highly developed and fine-tuned than stock jetting parts. Low and High altitude custom designed
triple taper needles. Main Jets included, Spare Needle Clip, and Dyno Tested. Developed and tested from sea level to 12000ft elevation, you can't buy this
from any OEM factory or aftermarket. It's JD's prescription for the headpipe blues.
