Heya Gixx1300R!
What is your thinking on using the Gen I TB's on the Gen II head, as well as using the Gen II airbox on the Gen I frame(i think thats what you are doing?)???
IIRC(and this is going back more than a few years
), didn't you run RC-51 injectors in your Gen I Busa? It was the 02-up(SP-2) 12 hole injectors.
