Hi CbCanada
My S2R800 2006 has all those mods, sans open and not drilled airbox.
A programmed Ultimap FIM ECU is fitted, no problems with fuelling, or low/mid torque.

I always use the fast idle lever from cold, it's very very rare that I don't.
The bike won't run on it's own until it's got a little warmth form a few mins of running.

Suggest you might have a tune issue.

Tune issue based on low torque after reflash?

I think your bike has a 5AM ECU, call Bobby at Houston Superbikes and tell him what's going on. I'm sure he can help.

Okay so is the general recommendation here a reflash?? That's will be expensive. It cost me $400 Canadian dollars for this current flash

More like the map installed at the reflash wasn't right for the bike.

Will the company that did it for you adjust/change the map, or do they only do a one size fits all?

My suggestion is first find out if you are running rich or lean throughout the range.  Then go from there.  At the minumum, at least do a spark plug check for color and idle CO with an exhaust analyzer as well as air bleed and synch.  Again, if all is proper you should be using the cold start lever when starting on a cool day, if you do not need it you are running rich.

I can check and read the plugs off idle I am familiar with that

Idle co exhaust analyzer?
Air bleed and sync?

Can you explain those two please

Your air bleeds have an effect on idle fuel strength and, since you have one throttle for each cylinder, flow must be equal for proper running.  This should have been done by the shop that did the work for you.

So it's same idea as carb syncing but instead it syncs the throttle bodies?

Yes.
