i was riding to work on the interstate and it started sputtering and died. pulled it to the side of the rode and when i could finally get it started again it only ran for a minute and died again. sounds like its only running on 3 cyl. bike had been sitting in the garage for a couple of weeks before hand. anyone have coil problems on these? carb problems? bike is a 2000 zx6r. any tips would be appreciated.
