I havent noticed it cruising...just when going up through the gears at moderate throttle.

It sounds like it is toward the rear...but you know how that goes...it is hard to tell exactly where sounds are coming from sometimes. Especially if they are faint like this one.

As bad70supreme said...and I have read it elsewhere...this could possibly be the belt...and I did change to a different tensioner and belt.

Any other ideas?
