Pretty cool, and it appears there were quite a few karts, and I think I saw a old old Arisco engine in there. Funny how karting and has evolved, at least the asphalt side of racing, into some kind of level playing field make it fair racing series with fewer and fewer competitors. The old classes were far from perfect but there were many entries sometimes TOO many!! If it keeps on evolving karting will be a memory, I miss the old way and the spirit of make it faster not todays spirit of level playing field.
Really neat video of street racing, do you what class that was?
