I was using a stock damper the last time we ran Lowes. During the Enduro the 35 year old rubber insulator gave up the ghost. The pulley left taking the belt with it. The surprising thing was that it didn't hit ANYTHING on it's way out! The first indication was the water temp going China Syndrome. Bryan pulled over and tried not to get run over. We rebuilt the motor as a precaution. Over all it was not a big deal for us but I'd hate to have been the guy in the SRF that was right on his bumper!

Obviously I now use the Euro damper.
