Replaced the belt today and saw 2 potential problems causing the excessive tightness and premature wear. First, belt tensioner indicator was mis-indexed by 25%, showing partial tension, when the belt was fully slackened. Second, when I replaced the tensioner I had forgotten how the shock absorber system worked. The shock can rotate the tensioner assembly and moves the roller pulley up or down to effectively de-tension/tension the belt when abrupt RPM changes occur, downshifts/upshifts occuring at the wrong time. I had transferred over the shock absorber fully extended. I wondered why I had to 'lever' old the belt into place before I even started to tension the belt. So I compressed the shock which gave me plenty of slack to install the new belt without prying it on, and then with the indicator properly indexed the belt *seems* to be much happier.
