G'day mate,
check the battery terminal connections, as well as the earth cable connection at the battery AND the chassis, to start with.
Just pop over to the new members section of the forum and introduce yourself . . . and tell us some history on you and your Busa.
Why rebuild the gearbox?
Did you do the work yourself?
More pics if you can.
