   my 2001 zx6r has a flat spot in the jetting between 8-9 grand in the rpm's, it has a muzzy's full exhaust , stock air filter, and has been jetted with the yosh. jet kit.
   i sync'd the carbs but it still has that flat spot.
   anyone have any suggestions where i should start?
   thanks for the help
   Bob
