I'll try to make this long story as short as I can. I live in Canada and last winter my wife and I decided to spend 4 months in the Rio Grande Valley in Texas and I took my 08 Ultra Classic which was still under warrantee until May 31/2010. Around Feb 15/10 I decided to have my bike checked at Rio Grande Valley Harley Davidson because it developed a rattling primary chain noise which to me sounded like the Primary Adjuster Problem. The bike had about 10,000 miles on it and I was about to take a 2000 mile trip to Big Bend and Back and wanted it checked before I left. The service manage had a mechanic take the bike for a ride and the mechanic reported back to me that there was no unusual noise comming from the primary. I suggested that he should have his hearing checked cause all my biking friends could hear it. The bottom line is that I've put on another 10,000 miles since that time without any problem except the primary chain noise. I finally had it checked out last week back in Canada by a well respected repair shop because I was tired of hearing this noise and always careful not to rev the engine for fear of damage. It turned out that the primary chain was the culprit. 7 links were very loose and as the chain turned you could see the top part become tight and loose between the sprokets which we feel made the rattling noise. $400 repair bill fixed the problem and of course no warrantee and I doubt if I'll be reimbursed. I'll be more careful next time not to let the warrantee pass me by.
