Needle jetting

[bighefbanshee]

I have a 01 banshee with the following mods:

 

Noss Head 21cc domes

FMF fattys PC II's

Pro design Pro flow with foam filter

V-force 3 reed cage

Stock air box with lid on snorkel removed

 

My current jetting is 280 mains, dynojet needle on second clip from blunt end, stock pilots 1.5 turns out on the air screw, approx 900 ft elevation.

 

My question is doesn't the needle seem a little lean? I had the clip in the third position and the bike seemed sluggish in the mid range and the plug was black. The bike seems to run better in the mid range with the clip in the second position, but it now has a bad bog right off of idle. I did a half throttle plug chop and the plug looked great? Should I switch back to the third clip or what? The bike did not run as good in the mid range but it also did not have the low end bog.

If its a low end bog, its not your needle, probably. Check your pilot.

 

How does your plug look with the needle in the second position?

turn your air screws in 1/2 turn.
