[F500] Mikuni Carb Tuning

[Edward Kramar]

   I would go to 5.0 or higher like 5.5 for autocross with a Kawi..
   Won't go faster than about 70 but get's there real fast.
   If you get on a course with long straight be careful not to
  over-rev the engine by taking the clutches into full engagement.
  Also I think chain is only way to get those ratios and 
  be reliable.   EdK    89 Red Devil
