Hello Cole,
I think AVL 350s had a true speed of 115kph, going by that you are pretty close to it. However, we did get better results when we tried few VM carbs. We tried VM28,30, 32 and also Flat Slide 30's. They offer way more crispiness than the stock BS26 carb.
For now, I think you can play around with the existing carbs jetting. I also think that you can push the mainjet till 110 and pilot till 22.5 (not sure about the pilot). My friend has a similar setup but he's got free flow exhaust and airfilter, which is pretty compatible with bigger jets.
Oh !! and we also got rid of the PAV and catcon - that helped a bit.
