Need help with needles.

[memphis2857]

Currently running a N3CH needle on clip 2. The bike is ever so slightly rich just off idle and then is pretty lean from 1/4 on through until I get on the main. Would a N3CJ help with this?

182 main
40p
0-1000ft
35-85* F
S3 head black insert
Stock Exhaust

N3CJ worked really well in my ,13. High comp cut head. Stock and gnarly exhaust. Tons of low end grunt. Smooth, crisp, and strong.

Going half a clip richer on the clip will improve your slightly lean 1/4 throttle up.. This would be an N3E(x)#3

A leaner diameter will help clean up the off idle richness. A W or J. You may need to adjust the pilot to maintain the idle and fine tune of the off idle response.

So a N3EJ or N3EW? Wouldn't the W be 2 steps leaner than the H? Happen to have an OEM part number for them?

W is equivalent to an I ... so slots right in between N3EJ and N3EH
