If you do go carbs, get bike carbs, they stay in balance far better than Webers.
Though, for the little extra work, and the far more refinement and better results, just go with ITB's.
For carbs, the easiest and most commonly used is Megajolt ignition, simply need a 36-1 trigger wheel, cam sensor if you want 3D mapping I think, and for carbs, you're better suited with something with at least a 38mm choke, 40 would be better, so GSXR 750 at the smallest.
That's what I can remember from my original plan, but was a while back so don't quote me on details lol.
