Jets should be at the mc shop today.

I have to give this up for now.  Be back later.

Looks like it works.  Pictures are too big.
I'm getting too old for this type of tech.

This is the third pic.

First picture previous post.         Float level gage
Second picture previous post.     Silencers cut to 10" oal
Picture this post                        Silencer exit end, 1 1/4" perforated tube

Floats set to 14 mm
Changed to 42.5 pilots

With 40 pilots very lean, popping on decel
With 42.5 pilots transition from idle to midrange seems rich.

I may have a fuel delivery problem.

Thanks Speeddog and Ducpainter for posting help.

This is a great forum.  Thanks to all for the help.

Often the way. Sorting one rpm range and having an issue on the overlap to the next fuel circuit. You fitting a jet kit? Needle postion, taper and root diameter via a Factory Pro or Dynojet kit may give you options. A smaller root diameter might let you get away with a smaller pilot. The oem needles are on the lean side with a large root diameter and very little taper if thats any help.

If the 42.5 pilots are to rich in the middle.... try to move the clip on the needle  up a notch    ex: if you where 3th notch from the top put it a the 2th notch from the the top .....

This will lean out the mix between 1/4 to 3/4 of the trottle.

If it dosent work well

Go back to 40 pilots ( assuming they don't pop at idle)   and move the clip position on the needle as needed .

Clip closer to the top = more lean
Clip closer to the bottom = richer

 [shot]thanks Ducatigirl
My needles have only one notch.  My bike is '01 M750.  My copy of the Ducati parts book (750 Dark) show notches. 
I can remove the washer on the needle, but going to think about this until tomorrow.

What needle is it?  Manufacturer and number.

[scaudill]

Mikuni symbol then 5C22.  The needle looks like polished aluminum.

Hot! Looks like a magnesium bodied race carb. Pops Yoshi.

Sounds like the needles are stock, so a good Dynojet or Factory Pro jet kit might give you the adjustability you need to play around with the settings and dial out the transitional issues. It can take some time without a dyno and EGA.

I'm a fan of Dynojet needles and Factory Pro needle jets.

5. Reorganizing the main fuel circuit to be more "linear". It looks like ducatigirl 100 did this.  Hey 100, you are welcome to share how this was done.

I guess I could share the "black magic" of this mood ..
