Triple Taper Needle for PWK 35

[sixfiveyeti]

I'm pretty stoked with my findings today fiddling with jetting. And thought I'd post. 

 

Stock Bore x Stroke, forged pistons (not sure if ported),

CoolHead with 22cc,

Trinity 2 into 1 Keihin PWK 35,

Airbox adapter and Pro Flow air filter spigot. Lid on (with snorkel removed) a few 1/4" holes drilled,

Fatty pipes and power cores out back.  

 

600ft above sea level  60 degrees F

 

48 Pilot (52 when in the 30's outside)

NFTH needle 3rd clip

170 main

1 1/2 turns out on the air screw.

 

So I had been happy running with this jetting with a straight taper DDK needle 3rd clip but noticed that no matter what clip I put the needle at, I wasn't satisfied with the 1/4 through 1/2 throttle range.  Mid range to top wasn't right either if I got the bottom close to where it needed to be.  I decided what the hell, Let me throw in one of these KX or KTM needles I have.  I thought for sure that I would feel bad spots in the throttle range but knew it had a slightly richer L1 area.

Surprisingly this needle is the best I've tried yet.  My power comes sooner in the rpm range and runs right out to the top without a hicup. Throttle response is super crisp and it's really brought my low mid power to life.  Top end still rips the same as always.

Ever try an EEK? What was the code on the Factory bike needle you tossed in?

I haven't tried the EEK needle.  I will be ordering one soon enough.  I just happened to have the NFTH needle lying around from my 2005 KX250.  I believe the needle is allowing me to have the nice fat 0 to 1/2 throttle while staying on the smaller side for main jets.  This is my first Banshee and I just put it together from about 3 storage totes a few weeks ago.  Guy I bought it from tore it down bought the 2 into 1 and coolhead and never got back around to putting it together.
