Do yourself a favor and get a good X ring chain and steel sprockets. Now, this part is controversial. I used go back and forth with Big Bill about this. I stopped lubing my chain and it is lasting much longer. My theory is with an X ring chain the lube is locked in the chain and oil can't get in when applied. All oil does is attract dirt and act as an abrasive to wear the sprockets. So in my opinion, do not lube an X ring or O ring chain. I found this by mistake, my old chopper had a 66 TR6C engine in it and the breather blew oil on the chain so I never lubed it. When I got the SM I didn't oil it because I didn't think about it out of habit and it is still on there with no oil. If you use a standard chain the it will need oil since you have no seal to keep lube in and when oiled lube can get in because there is no seal to keep oil (or dirt) out.
