Default Running CVP velocity needle. shims?

Got some pics of what was and what is.....

This is what was in the bike when i bought it and it had the carb fart.

Don't know what needle it is but it had a plastic spacer 0.8mm



I then went for the CVP velocity needle without the plastic shim and this appeared to solve the farting.



I recently added some really short exhaust pipes and lost power which i live with but talking to a friend he said try a shim under the CVP needle and see if that improves mid range. TBH couldn't really tell but i guess better.
The shim is 0.6mm and he gave me 2. I have been running one but now have the fart back.



No shim but recess in slide.




Jets are at 45 pilot 185 Main. if i go any bigger on the jets i lose about 20 miles of range.
I have the CVP emulsion tube, the CVP needle jet, EZ mixture screw about 2 turns out.

I am running the stock rubber breather pipes that run back into the inlet manifold. Some say to modify this on the XLforum.

So my question is what, if any, shim should i be running?

Thanks
