For anyone contemplating this conversion, it is not that simple.

I have just successfully installed a Honda GXV390 into an Evolution Mk2A.
Would I do it again? Probably not, due to the modifications required.

Re: Exhaust.
The motor has to go "sideways".
The exhaust on my Honda motor model couldn't be reversed.
It has two mounting bolts, and I spent days welding a custom exhaust manifold out of steel water pipe. It needed to be low enough to go under the motor fins, exiting the frame in front of the foot pedal.

Notes on wiring to follow.
