Nice little project!
A mate of mine and I were thinking of building a go-kart/offroad buggy. We bought a 200cc motorbike as an engine donor for £30 about 6 years ago, nothing ever came of it though as we just rode the bike around a quarry until we had all fallen off it. :haha:
Quite tempted to have another crack at getting one built, should be a decent laugh as an offroad toy.
