Re: A project I have in mind...(but I need a little help)
I'm gonna hafta agree with Jax2A on this one. If you just want to build something that gives the vibe of that Marsh, then yes, you can do it and for not too much money.
The bike you posted would make a very nice motor bike but I would suggest one of the bikes with 2 top tubes, one above the other. With that frame you could make a tank that fits in between the 2 top tubes and just use a Chinese 2-stroke kit. The tank alone would help give that Marsh vibe, a simple paint job and you're good to go.
