Looking at getting a running 1990 600 ninja and turn it into a quad. Any1 knoe a frame that will work for this with little or no fabricating needed?
What if id keep the main frame of the ninja and fab up a front end(suspension steering etc) from say a yamaha warrior. Rear I was just hoping to find a swingarm that would match up
Just because you can do something doesn't necessarily mean you should. I see home brew street bike/quad experiments pop up on Craigslist occasionally, they are usually dirt cheap because they never turn out well. If your only goal is a stupid fast quad build a Banshee, that way you might actually enjoy riding it.
