Well, never thought it would happen, but i did today. Out of nowhere grinding noise from cam chain area. Sounds like a cam chain. Noise increases, speeds up with rpm. Sounds like something rattling inside. I just had valve check done by Action Yamaha in Metuchen, NJ. Stay away from them pending the outcome of this. This may be coincidental, but nonetheless. I have 29K miles now, 2013 is model year. Should I attempt the ride back to NY or find a good local dealer, how funny is that, god local dealer? This could take at least a week. I do have YES warranty, for what its worth. Any reputable places within 100-200 miles of ouray?
