New bike, what to do?

[Guest]

Sounds like too much side load has been put on the bearings (Overtightened axle, bearing improperly seated, ...)

Come to think of it I did take it for a trip around the block to make sure all was well and when I got back tightened up the chain a little so I may have overotrqued the axle then

So I figured out that the noise is coming from the seal that goes just outside the bearing in the sprocket. It also doesn't make any noise after a few mile ride, only after about 15 - 20 miles does it start to make noise. Is there a specific orientation on the left hand side spacer? Otherwise I think I'm going to just keep riding it and let the seal wear until it fixes itself
