Does it stop when you pull the clutch in?

Take the outer primary chaincase off first and check the chain tension. If it's too slack it makes and awful rattle as the chain tensioner adjuster screw clatters against the inner chaincase, but it's an easy fix, unless your primary chain actually needs replacing and there is no adjustment left. While you're in there, also check that the alternator rotor isn't loose on the crankshaft.

Also check that the alternator rotor woodruff key is not sheared; which does happen when the engine backfires.
