Looks like a YTM225. If it has reverse it is a YTM225DR. Nice machines in my mind. If it isn't running, just check for a spark first. Roll it around and listen for any odd noises. Put it in 5th and try to push it that way you can hear the tranny. Bring a can of starting fluid with you. See if you can get the trike to pop. I think if it is complete it is worth around the 300 being asked. Parts aren't too hard to find and there are at least of few of us on the site that have torn into these machines.
Anyone know of a new project machine for me around Wisconsin?
