My Kawasaki ninja 600 won't run right I have cleaned the carbs several times and every hole is clear in it but still will won't start back up after its been idling for a few min it also will not rev up very high either so could there be anything else wrong but the carbs, it has fresh gas and new spark plugs that all get good spark. thanks @
