I've avoided commenting in this thread because it really isn't my main purpose in life to make people feel bad. But there are some obvious questions about the situation, and some bad advice as well. First, if we ASSUME that Dealership #1 didn't fill the tank with oil, how do you suppose the bike managed to travel an additional 1400 miles before it lost oil pressure? Second, and likely to be the first question Harley might ask, if Dealer #1 didn't add oil or left it extremely low, why didn't the customer notice this during the routine oil level checks over the subsequent 1400 miles? Third, I haven't seen any mention of a response from Dealership #1. Have they been contacted? If yes, what did they say? If no, why not?
As for the advice to demand a new engine from Harley, or even better the purposeful destruction of the engine to force H-D to give him a new one, folks need to try to understand basic responsibility. Dealerships are independent businesses, not part of H-D, and H-D isn't legally responsible for a dealerhip's mistakes. IF this dealership didn't fill the oil tank properly, they have some responsibility to the customer, but H-D does not. I would most certainly agree that the customer should contact the MoCo and explain the situation and even ask for their assistance. But I don't think that starting out making "demands" will get any sympathetic treatment. Considering how Harley treats some folks with totally legitimate warranty concerns, I don't think I'd start out with an attitude and expect any help in what appears so far to be a very iffy situation. And btw, without going into the obvious ethical and legal issues with the "blow it up" solution, what happens if H-D finds out how that engine came to be destroyed and voids the warranty? I'll tell you what happens, you get out your checkbook and write a much bigger check.
