I was just wondering if your guys cog belt sit right in the middle of the cog teeth on both pulleys. My top pulley belt sit on the end not overhanging but right on the end. I would greatly appreciate pics of your cog belt setup from different angles if you could so I can make sure mine was on right. Thanks

 

That's where mine is as well and no problems after 7-8K.

 

That's how mine is too. Although, my pulley may be too tight because I can't turn it manually with my hand.

 

You mean the idler/tension pulley?

 

The idler pulley has raised edges and will not let it run off to one side . So as long as it not over the edge of one of the other pulleys...your ok
