Just the other day coming home from work, at the stoplight my 12r started missing, or sounded if running on 3 cylinders. It only seems to do it sometimes. 28000 miles on bike so far. just put new set of plugs in it not long ago. You think maybe its time for some new fuel injectors? Wouldn't the fi light come on if so? Never ran any fuel injection cleaner in it before ever. Maybe i should try that first?
