Have you been in contact with Yamaha customer service or just talking to your dealer. You need to escalate this as high as you can directly through Yamaha. They normally take care if their customers with an issue they know is a common problem. This will hurt them if they don't handle these cases accordingly. It sounds like they are just going to let the bad engines/rods show themselves and let their loyal customers take the brunt of the engineers mistake. Selling us machines with the Turbo option then telling people to remove the turbo after they fix it sounds like sales fraud.
I'd want more than a full refund, I'm thinking they owe for damages, towing, down time, they know full well they have a problem, they are keeping their head down and hoping it goes away.
