This is my custom 1971 US90.
It has a 125cc stroker kit, bottom end cam, cobra exhaust and rejetted atc110 carb. Most parts are from Dr ATV except for the stroked crank from powroll. With all the stock looking US90s around I wanted to build something a little different. I brought the bike complete for $300 minus the front wheel from a wrecker who said they were dangerous and wanted to get rid of it quick. I have all the original parts except for the front wheel but prefer to use it like this. Id rather ride it than look at it.
