For all of you non Harley fans, the motorcycle folks have a chain lube much like John mentioned. Sprays on as an oil , turns to a grease. It's important to Harley folks that their chains stay operational, particularly on long trips. On the road chain repairs can be messy and often inconvenient. You buy it at motorcycle stores, of course. I use it on the chain drive of my garage door opener, and occasionally other spots like the hinges and pivots, etc...good product. Bicycle stores also carry a chain lube but I've never used theirs so can't comment.
