FMF Jet Kit vs JD Jetting for '07 WR450F
Posted February 08, 2010 - 07:30 AM
Can I expect the same performance/results?
(It is half the price of the JD Kit.)

Also, James Dean kits use Kehien jets, DJ use their own ones, the sizing id's are not the same.

Maryland. Sea Level to 3000 feet. A. Thanks a lot.
I presume you have all the free mods done....
Try the following:
168 main (maybe 165)
fuel screw 1.75 turns out
Stock 2008 YZ Needle in the middle (4th from the top) clip.
You can mess with needles but I have found that hte stock YZ needle does just fine.

JD does in fact use Kehin jets. He does not use another brand or his own. You'd be foolish to try and reinvent the wheel when all the work is already done for you. His needles are substantially thicker requiring larger jets be used than what would be necessary for the Kehin needles.

I was CHEAP and bought my own jets and jetted my bike...while the end result was equal to my 06 that is JD jetted, it did take a little trial and error....BUT I did save 40 bucks
