You can’t buy this from any OEM factory or aftermarket. It’s JD’s prescription for the headpipe blues.

" We installed a JD Jetting kit on the 2006 CRF250 and followed the intructions for the accellerator pump. This bike has carb issues from running a 40mm carb. Once we chose the Blue needle and adjusted the mixture a bit richer the result was amazing. The bike picks up right off idle and since the JD kit allows you to run a larger main it snarls all the way through the range. Impressive. “
