anyone good with diagnostics

Just curious... I'm working on my bike and having issues with unfortunate metallic sounds in the motor... but it doesn't seem to be valves and the sound doesn't seem to occur when I pull the plugs and rotate the pistons through a full stroke by turning the wheel... weirdest thing... and I get the sound when I only run one cylinder... vertical and horizontal.... soo... ummmmm

I'm down to checking the alternator nut next but not sure where else to look...??

Could still be connecting rod stuff but it doesn't happen when the plugs are out and I turn the wheel while it's in gear... belts are good...

Any thoughts...

I'm in lower manhattan... and i have tools... a place to work... and a couple of people helping me... but as of yet haven't gotten anywhere...
Sunday I'm going to pull the alternator cover and see if the alternator nut is loose... as it seems the metallic sound is gone when I pull the plugs out and turn the bike over...
Not quite sure where to check next... I have to go to a wedding today but I got your PM and I'll try you later Howie.... thanks
