Here's the set-up...
2006 KLX125
150 big bore kit
Stage 2 HotCam
Port matched head
PC exhaust
Top of air box cut out
Screen in
Stock air boot
PWK28 carb
38 PJ
130 MJ
NAPE needle
Clip 2nd from bottom
Air screw 2 out
500ft above sea level 90-100 degrees
So... I just installed this carb after struggling with the VM26-606 for months without being able to get rid of a mi-range bog issue. After some tinkering with this PWK28 carb for a bit, I'm verry impressed and have it running very well mid to top. Much better than anything I ever had with the VM26.
My issue is this... I can start it first kick when its cold. No choke. By cold I mean ambiant temp. When cold, it seems to run great through out, and throttle response is great. As it warms up to operating temp, the bottom end (idle to 1/4 throttle) becomes increasingly "stuttery". Don't know how else to explain it other that it stutters when I. Hold it constant at any given throttle position between idle and 1/4. Then if I kill it, it will only start with choke.
Any help would be greatly appreciated. Thanks in advance.
