they were a rocketships back in the day, my dad had one for years, it had good days and bad ones it takes a while to get the jetting dialed in even though its charted and what not its not quite what you need, my dads always seemed to run rich but when that thing was leaned out right it went pretty good gor the year. if your doing hills dont stop and get a hell of a run, but it would make a good lake riding or trail sled for cheap. if you do have one you should mod it the latest trend is to paint them black put monster decals on risers new tunnel etc. lol they look sick like that. i heard they only made 70hp unlike 80 up there.
