I have a 2011 Fat Bob that I had the stealer install a new chrome sprocket on. When I was riding the bike home I noticed some vibration and some low rpm lugging that was not their before the installation of the sprocket. I took the bike back and the tech test drove and said He felt it but nothing was wrong to bring it back if it gets worse. As you guys know everyone knows their own bike and I know something was different on mine so on closer inspection it looks to me that the tire or the sprocket is not straight. When I look from the back of the bike the top part of the sprocket is leaned inward towards the tire and the bottom of the sprocket is leaned out bottom line the sprocket is not perpendicular. Would you guys think the sprocket or tire is misaligned and could this cause the conditions I have mentioned above.

 

This I would like to see. Can you post a pic?
If it is much of an offset the belt should either come off, or be torn apart.
Either way, if it is off enough to see as you stated, remove it before you ride anymore and fix it.
Lot's of threads on here about sheared pulley bolts, so do it right.
