Moped Army

Whats up guys! New to the forum board.
I just picked up a Motobecane 50v (1979) and already got big plans for her... Picked up the bike for $250! without a carb though, so I had to throw in a dellorto. But after riding for a bit I must say I am disappointed in the power.

My question, I've searched a bit but so far I haven't found anyone doing any swaps, i.e. Kawasaki kx85 => Moby. Thats what i'm looking into doing, but I haven't been able to find any info on the subject.

Here's the picture that got me into getting a moby, although I do realize I have the wrong model.
