Belt noise can be a tight belt, a bad pulley or roller, the back cover being loose and touching the belt.

The rollers are the smooth ones -- no teeth. One is slightly clear of the belt but does spin from the belt spaping it. A fellow driver was asking me the same question last year. Turned out to be the roller that just clears one of the belts. Could hear it spin down for almost a minute after he shut off his engine.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?
