I have no experience with the bike, except for the forks and wheels.
Eight valves and counterbalancing was great stuff but unfortunately it was air cooled and 750cc, just as water cooling and the shift to liter bikes were coming on.
The front end is almost straight off a TZ750, larger diamater fork tubes and larger disc too, all on a nice Borrani/Akront knock off wheel. Those Yamaha iron caliper brakes, IMO were the best of the era, although heavy.
The rear rim is a nice piece as well, but it is 36 holes.
