Take off the seat, look to make sure the tire isn't rubbing into the mud guard that protects the battery area. If it's too close adjust the shock to the highest setting. Might not even be the belt making noise. If the tire has rubbed deeply enough into the guard it will knock off the alignment of the rear tire.

Just went through this.

Supercub -- Have you have had a tire change?? I have that wobble you describe -- about a mill and half out of true...Found it like you -- on a stand, doing some regular maint....AFTER a tire change...The bolts the pulley is attached with have flat steel washers between the nuts and the pulley plate...My thoughts are that the bearing housing "may" be cocked on re-installation..????? Just a thought..the coush-rubbers may be misaligned as well with that?? I've checked into the pulley run out but no definitive values so far. However I am of the opinion that there should be little if any pulley deflection...

I have used a material of late made by Lyman, who make shooting products(bullets, loading equipment and the like) They have a bullet lubricant which is a waxy substance with graphite embedded...Works pretty good, and better I think than the heat sink compound I was using....Might work??!!

yes had a tire change at the first of the year but it was fine for a while,an then it started.My pulley wobble is about the same.I am going out in the garage now to try again.I do not think the pulley should have a wobble this moves the belt around making it rub an squeal.I would think
