It's me again with questions from brainbox....

If I was to swap the engine in my 250cc gionvanni with a Honda XR200 motor, what should I also change.

Will the Carb (Mikuni) work with proper jetting I suppose. I found out the proper jetting for the XR200.

Will the wiring harness work or should I get a new harness for the motor?

Anything else I should look for.

Thanks in Advance
