OK, here we again and again and... 90,000+ miles on my '08 SG and 80,000+ miles on Mz Bling's '06 1200C Sporty. I've completely cleaned the belt and rear pulley twice within one week with hot water and Dawn detergent using a toothbrush with a very good rinsing. A slight squeak comes back and have read different opinions: 1. use a belt dressing or Napa syl-glide is a good fix 2. Never use a dressing on a serpentine belt 3. replace the belt and rear sprocket I hope I'm not opening a "beat up" can of worms but thinking a little dab of Napa syl-glide might be cheaper than a new belt/pulley. Any experience yay or nay on the Napa product or belt dressing? Happy Memorial Day Weekend!
