Here are some pictures of manual tensioner installed in M1100 Turbo. These are the parts used on the 600 Sno Pro race sled. My sled has about 275 HP and I checked the chain at 300 miles and 475 miles..estimated. first inspection all good. Second not so much. I knew it was not if but when. IMO the tensioner allows the chain to jump damaging links...and in my case the top sprocket. The pieces damaged most other parts but sled was still running fine.
I think many are running with broken parts prior to the big jammer.
250 miles all good
475 miles nos so much
