Chains should be lubed at least every 500 miles. Since it took one-half a year to roll 500 miles, you might consider lubing every month. Riding on wet roads, in rain etc will wash away lube and rust your chain. Especially since you don't apply lube to it but for every six months? Every three hundred miles is betterer. Use Maxim Chain Wax. Spray on wipe off.
Chain noise could be due to misalignment as well. Too tight too loose. Do not rely on the dealer to inspect anything on your bike or to lube anything or to sync your carbs. You would be well advised to check the oil plug to make sure it is tight and to observe that the stealership did not overphil your oil too. grrr. The best thing a dealer can do is to say NO. No they don't want to work on your ride. No they can't work on your ride, and NO they do not have OEM parts in stock. After all honesty is the best policy. All most stealers want to do is sell bikes. Well dealers can do what they are good at. They can kiss my hairy buttocks cheeks.
I so love dealers.
