Answer
Hi Richard.
 What you have asked is an awfully broad question, but I belive that I know what you are getting at.

Remember that an engine is an engine and you have to realize that people frequently use different engines in applications that those motors were not originally desined for.  I have a friend that powers his airplane with a Subau car motor, for instance.

It is not the vehicle that the engine is in which determines what the engine needs to run, but what the engine was designed with.  Then you modify from there to make it work.

Start with the motor, itself.  You need that and all of the basic wiring to run the motor (ignition system, charging system and any other required electrical).

From there, you look at the application for that motor.  You are converting it from motorcycle use to buggy use.  What changes, if any need to be made to the final drive?  Do you leave it as a chain drive and modify your buggy to suit or are you wanting to convert to a shaft drive and change the final drive on the motor to suit?

That's what you are looking at.  What the buggy needs, what the motor needs and how you combine the two into a working machine.

I'm sorry if my answer seems a bit vague, but every problem is not always black and white when you are talking conversions like this, and so what I have tried to do, instead, is to show you how to jostle your own mind into solving the problem.  You see, I firmly believe that if I tell you how to fix the problem you will be up and running, but if I teach you how to analyze the problem, then no problem with this or any project will be insurmountable.  Just remember that our ability to reason and think logically is what sets us above the lower life forms (politicians, timeshare salesmen, etc.).

Good luck.
