Cool.
What UFO's are you using? 2.5, 3.0 or 3.5 cut out?
Over here, we are a couple running VM38's. We both use Q2 NJ. If leaner, Power went Down in the 1/4th throttle openings area. Funny thing is the other one does not use UFO, but Stock 2.5 slide. I use UFO 3.5. Still we both ended up at Q2. I think I have 12.5 or 15 pilots. I think he has 35 or 40.
I am not saying Your intake runners are too short, but they may be. I did a lot of dyno testing for the purpose of finding the shortest intake runners lenght as possible (for fitment reasons) befor Power in the low/mid went Down. My Intake runners has then Ramair 70mm fitted outside the silicone tubes for Maximum air flow. And I found the minimum length to be in the 200mm area, before Power went Down.
I have about zero experience With TM34's. But I can assure you the 38's will boost Power at all revs all the way from 3000 to max versus VM's. So, I believe you will feel Power icrease over TM's as well, but maybe not in same extent. Make sure you are able to give 100% full throttle. I had to adjust the splitter. It is a couple of horses to be gained there as well. And the perpendicular to bore carb position also gived you a Nice little Power gain over conventional carbs position. Don't know exactly how much though....maybe 3-4 rwhp???
What heads do you have?
Oh.......and Your bike looks GREAT by the way, I also like those pipes very much.
Good Luck With the tuning

Using 3.5 slides with Jim's UFO's. The motor was 4 stroking with Q-2 NJ and plugs were black. The intake runners are about 130 mm long, could have got longer ones in there I guess. I got away with shortening the outer throttle cable sleeves, carbs will open to full throttle. The port / head work was done by Tony Nicosia. Pipes are FBG. Thanks again for your advise and jetting info....
