Good info. This was before I got into skis and did not know any of thatThat race was a big deal back then. Yamaha was just trying to enter the standup market. Kawi was running the IJSBA, I dont think they would let Yamaha participate. Chris Lauber and the Busch cup started sanctioning with the APBA. This was back when the IROC auto series had some traction and they played off of that idea.
Busch cup was a GREAT tour, with races throughout Florida in the "offseason" (Winter/Spring). Many of the big west coast names would show up too.
Thanks for the link.
