Step one; buy a big monkey manifold.
Step two; cut it up, weld it back together and turn it on the lathe to fit an original Honda carb boot.

Step three; mount it and add CB750 carb modified to take a normal throttle cable.

Oh, step four; tidy it up, but I still have to do that to the whole 120cc motor.
Everything will be glassbeadblasted to match.
And now just keeping my fingers crossed that I can get this carb to work. My dad has used them before on 125cc motors, so luckily I can peek at those for the jetting.
