I recently purchased a Boxxer XL. After 175 Hrs the belt tensioner basically "exploded". The part was replaced under warranty (which involved 6 hrs of driving to and back from my distributor). 13 operational hrs later the whole pulley system flew off while cleaning and lodged itself between the exhaust and the heat exchanger. I'm concerned about collateral damage to my new machine from flying projectiles, not to mention the drive for warranty repairs and lost business. Has anyone else run across this problem and found a solution?
