carbed bike engines megajolt?

[Talonmotorsport]

I'm looking to build some off road go karts to use round the farm so I've been looking at 7-13hp honda engines,clutches etc. Looking at the prices I then thought about 400-600cc bike engines and found 600 carbed bandit engines with clutches and gear boxes for the same money. How ever I know next to nothing about bike elastictricery as we've only ever mounted bike lumps not made them run.
So what I want to know is can you use megajolt on bike engines or am I better off using the original loom etc?
