When you say bag of shite, what are the symptoms ?
My MC21 was doggy off idle and the first 1/4 throttle. Bit smokey and fluttery when you go to take off. Felt too rich.
The air screws were set at 1-1/2 and 1-3/4 with factory jets. I changed them to 2 full turns out and it was definatly crisper, and alot easier to take off.
Mine has the same mods as yours. Air box, PGM and GPS splice and different mufflers. Std jetting tho
