Just installed a 3.3" RR pulley about 2 weeks ago and I am experiencing a lot of belt dust. My stock 3.5" never left any belt dust
My replacement belt aslo was a bit longer even though it was the same part number.
So there is a significant difference in slack. Would a shorter belt help? Likewise, it took me about an hour to get the new belt on while struggling with the damn tensioner.
