You can use any carb on a motorized bike if you can build the manifold for it. Su Carbs are my favorite since you no longer need to buy jets for it as you can change the dashpot oil to different viscosity's and amounts to suit your needs while you adjust the bottom jet

It seems like most motors can handle up to a 21mm and if you have a built motor that seem to be able to use even larger carbs.

look like standard keihin... 16? 18?
course theyll work. and jets are readily available...
