what is the hot needle nowadays??

hey all.. .i had a drzE back in 2001 /2002 and was a regualr on this forum. So just wondering... back then the hot needles were first EKP then EMM. James Dean helped test and develop those and was the genisis of his company as far as I know. I tested both and settled on a ELM (OEM yamaha yz426 needle). is EMM still most popular (aside from JD Jetting needles)?

EMN rich .... EMR leaner

I got good results with the emr over the emn with the db killer in the muffler.

Exhaust is a Staintune, full system.

is the MER similar to the needles in the JD jet kit? I havent seen anywhere that JD gives the numerical (letter) values to his needles. I am curious about this.

Eddie has recommended the JD blue needle or EMN in similarly modded set ups with the Fcr carb...

hey thanks for that info craigo. Any idea which needle the JD red is similar to?

The Jd needles are multi taper and not relevant to kehin codes...

I know EMP ,EMR and JD red are not the same...

Either will work but require different jetting...
