Ahh, did I notice the "sound" more clearly when you leaned to the right? The "rattle I think I hear is at crankshaft/piston speed..?

Sounds like my skid plate without and double sided foam tape stuck between the frame and plate.

I would just get the manual cam chain tensioner. Even if that doesn't solve your problem, its a good idea to get one anyways.

Just put my Krieger manual cam chain tensioner on yesterday. After years of listening to all those rattles, thinking that this is the way it is suppose sounds. Now everything sounds perfect. No noises at all.
