I own a 2014 Chieftain with 27,700 miles; purchased 11 months ago with 23,300 miles from the Indian dealer in St. Petersburg, FL where I live. . Heard an unusual rattling sound on the right side of the engine and took it in to Indian dealer; was told it's the tensioner, it must be replaced and I should consider replacing the chain as well. I'm not a mechanic and have only been riding for two years (rented several bikes before deciding on the Chieftain) but it seems a little early for this to happen at 27700 miles. I know it must be fixed. Comments & advice appreciated on how soon this may happen again, is it a chronic problem with this model, etc. Thanks.
