Ugh.
Pilots should be around 25-27.5, add a size for the VF reeds. The toomey provided needle has a very easy to tune taper that has worked well with my setup through a few mods. It may be helpful to get your hands on one if need be. Not sure how your tuning is going up to that point.
I'd also recommend giving consideration to adding 1/4 turn to the clutch side carb since the water pump and trans fluid are right by the cylinder. My pipe was about 20° hotter just after the first bend and my cylinders (at the outside transfers) were about 10° over that on the other side at idle. 1/4 turn has gotten both temps down to less than a 10° difference on both pipes. I did check to make sure the carbs were synced before all of this.
Are you running an airbox lid? I found mine to do very little to protect against water, so I removed mine (we never get near water anyway). It provided a noticeable gain in power. Had to go from a 280-320/330 (summer/winter) main jet, 1 needle clip position, 1/4 turn.
