Broke a belt, dealer put in new belt rollers and sliders. Went to pick up but it was making noise. They were supposed to put in new clutch. Rode 25-30 miles. On level road at 25 30 mph it slips smelled like burning rubber. Pulled cover off , got a freezer bag full of old belt chunks out of air tubes. Pulled it apart, sheaves,rollers and sliders looked dirty but look ok. I'm wondering if belts wrong length since it old style pulley.
