Noisy cam chain?

I just got my KZ305 running last night and it runs great! Only thing I noticed is that it makes a chain sound while running, like the cam chain is loose or something. Is this a normal sound for this engine or do I need to make adjustments?

I'd ask here as they seem really knowledgeable about the twins.

Also do you have a shop manual? this will show how to adjust the cam chain. If not www.repairmanual.com should have one.
