CVO Ultra 2010 - had it's first service at the dealers at 1000 miles. At 2400 miles it started a rattle - linked to the rpm - like an exhaust clamp or the horn cover was loose. Checked all over but couldn't find the source. Rode a bit more then noticed that the oil pressure was fluctuating, independent of revs. After I saw it drop to zero a couple of times I pulled over and checked the oil - dip stick dry!!
Got the bike taken to a different dealership and when they drained the tank there was 1 pint of oil remaining (18oz/550ml to be precise). So where had it gone? No leak, the bike has always been as dry as a bone. Could it have burnt the oil? It didn't burn any in the first 1000 miles and surely if you're burning that amount of oil there'd be signs. So if it didn't leak it and didn't burn it you have to ask how much was in there in the first place? Refilling the oil and replacing the filter has "cured" the rattle, but having spent more buying this bike than I've spent buying all the cars I've ever owned (30 years worth) I'm not in a good place right now
Hopefully, you're had a chance to practice your "deep breathing" exercises and can approach this issue methodically.

Over the years I have had to deal with manufactures with similar issues. I have found that if you keep notes, and document everything you can; you MAY or MAY NOT need it for the future.
Don't assume the dealer/factory is out to screw you, and approach them with a friendly, positive attitude and you will gain much more than using threats.
I DON'T condone being dishonest, illegal, immoral.
It's best to be very patient, and give the parties a chance to review your situation and make it right. Dealers do not want to lose customers, neither does the factory, they all want to stay in business and most are willing to do what's reasonable to keep a happy customer (you can't buy this kind of advertising!).
Go through your "chain of command" and most of all be patient.
This is just MHO, and has worked for ME.
