OK i did it but it still boggs right of idle when i whack the throttle open ! Is this a fuel screw problem or should i try the #6 position? The popping on decel is gone.The temp today is low to mid 80's.I really don't notice much differance in power compared to my NCVQ needle. I'm at 1 3/4 turn on the zyp tye. With the 45PJ 168MJ.
The Red marked needle #5 with a #42 or 45 pilot and 168 main should give the response you're looking for, 1 1/4- 2 turns out on the fuel screw. Use the fuel screw to keep it running clean at idle, too rich and the response will suffer badly. Different models have varied fuel screw settings with this.

This is heading the same direction...
Yes, go to clip #6 on the red needle and drop the pilot jet to a #42 (or #40 if you were certain that NCVQ needed a #40).
This is not typical of most setups. Are you giving the bike a good ride period to warm it up? Snapping the throttle on the stand is not a true test of riding conditions.

You are right in the zone of most riders and should be thinking of how it performs under normal riding conditions. Snapping the throttle open on an FCR carb is asking for problems, when the carb is not a CV type and has a relatively big bore. Careful tuning will allow it within limits.

Your profile says your bike is bone stock, have you pulled the grey wire yet? My bike stumbled and missed terribly at steady, low throttle openings until I did this.

The sputter is usually a sign of a rich condition. Try the next leaner (higher altitude) setting to see if it changes much, if any.

Can I simply raise the C-clip to the 3rd notch on the blue needle? Shouldn't that lean it out one step? Or should I leave the needle alone and go to the next leanest jet? Also, the bike has all the free mods with the GYT-R insert, which might change the recommendations. Actually I haven't done the grey wire mod Lip Skid. Maybe I'll give that a try next.
