Interstate with annoying rattling noice

[Dag]

It`s coming from the alternator side of the engine. Maybe behind the alternator.
This happens only when the engine is cold, and dissapears after less than one minute.

I`m not 100% sure, but I dont think it comes from the clutch.
Could it be the chain to the oil pump?

Any ideas?

Thanks

My Interstate has rattled when cold since I bought it with 6,800 miles.  The noise disappears quickly as the engine warms.  I've owned the bike for 9 years, and it now has over 93,000 miles.  It used to worry me but now I ignore it.

I've had the heat shield, located beneath the foot pegs, rattle. I don't remember much but I tightened things up and may have pulled the heat shield out a little bit (bent) and that fixed it.

I doubt it is the oil pump chain, I had the guard on the chain come loose a couple years ago, noise got worse as the bike warmed up. Fix was the bolts on the guard had come loose. Must have been put together on a Friday at 10 min before quitting time.

Problem solved. It was the alternator.

Glad to hear you found it.

But what part of the alt? the whole thing, so tightened the mounting bolts, or ??
