I did some hill climbing on some few moderately steep hill and my a35 spun real bad when it shifted to 2nd it spun. Got home now when not running on the stand if i turn pedal forward slowly you feel quick slip and then the bell catches and slightly klunk sound? Did i finish off the drum bearing an bushing?? Alot of metal dust in fluid after the hill?? Also small real tiny piece of copper looking metal barely visible??
