My 1996 r1100rt started to have sluggish starts like a week battery. I had 13.65 from the alternator so I assumed it was a week battery. So I replaced the battery and cleaned all the to the starter. After that I have had the same issue where it starts but is sluggish to start. The starter has only 27,000 miles on it. Has anyone had issues with the starter going bad in this way?
