Wow, that's a beauty! I have always liked the red white and blue schemes on Hondas. Enjoy it!!
Almost forgot about the noise: could be tight-spot/seized links in the chain. If it was as rusty and neglected as you imply, you may just want to replace it with a new one (if that is your problem). A quick way to verify: with the bike up on the main stand, spin the rear wheel slowly and watch the chain where you would normally check the slack/adjustment. If the chain goes from properly adjusted or a little droopy to ultra tight, you've got a bad chain. If in doubt, check your chain slack several times in several places. If it is significantly tighter in any one spot than the rest, the chain is beat. If not, look elswhere for your noise.
