    Put in another factory compensator. Be sure the spring pack is shimmed for the max amount of preload.

    Please post pics of the carnage, so that the rest of us M8 owners will know what to keep an eye out for. As for the compensator eliminator sprocket, I used on on my 2015 SGS and loved it. If I were going further with the performance mods, I wouldn't hesitate to install one on the M8 too.

    A new compensator should not need to be shimmed, but I would check this:

    18flhxs, did you experience any noise or abnormal rotational sounds prior to discovering the damage to your compensator?

    No. It should be able to take that no problem. Lugging the motor at heavy throttle is worse on the compensator. It must have been defective in some way. Just put in another one and inspect the spring preload.

    So to update my last post,i ordered bakers compensator assy. And the attitude adjuster but wont have them till oct.3.i installed a solid sprocket to try to finish out the season but with that and the factory chain tensioner the chain is way over tightening, so looks like that plan was foiled.adjusted the chain tension to factory specs. Put about 100 miles on it and all was good,pulled the primary cover off just to check and the chain was tight as a banjo string.re adjusted it again and did about 85 miles real easy and checked it again and same thing way to tight,cant have that.so now it sits,for now.
