250-500cc Jet needle?

I have a 2012 wr 300 with the stock carb. Problem is i need a richer needle, the clip is in it's lowest position and it's still a little lean. It has the "gay" needle now and i can't find it on the net to compare specs. I don't need a whole $100 jet kit just a richer needle. The jetting chart says use the "red" needle, what part number is it, is it richer, if so how much richer is it?

"Red Needle" refers to the custom JD needle supplied in the JD jet kit. It is my understanding that the problem with the 300 jetting is the needle and the needle jet, both are supplied in the JD kit. The JD kits come with a blue and a red needle and red is the leaner of the two.
FWIW, when you buy the kit you aren't just buying the parts, you are paying for his time on the dyno figuring out what works.

The needle jet is small so jd sends a richer needle jet along with his needles that match it. After richening that up you are going to want some leaner pilot jets so after it is all said and done the kit is a good deal.

get the JD kit....it's totally worth it for several reasons.

32.5 PJ
blue needle @ #3
