I had one of those, I put a comet clutch with srv specs and bored the carb and used a wider belt from a cat and it ran pretty good, the track is 16 inch wide and no lug and the rear skid sucked,had a lot of fun on it,we called it the lead sled cause it was a bit heavy and had e start, used it as a backup when I would blow my piped 94 vmax up when new.
