JMO, We pay a premium for our CVO's and to fit after market parts to eliminate any premature wear/damage!!! 
However the M6 tensioner works well retaining force on the primary chain at varies loads. 
Can somebody give me more detail on how the OEM tensioner over ratchets.
Aussie - if you accelerate quickly to a high RPM, then decelerate quickly keeping the clutch engaged, this will introduce some slack at the bottom of the chain. The ratcheting tensioner can ratchet up to take up this short-duration slack, and then it will stay there. This can make the chain too tight - which will pull on the sprockets on both ends, and a too-tight chain is hard on both the compensator and the clutch... although the compensator will very likely be the first thing to fail, since the clutch is so much bigger and stouter. An over-tight primary chain will also wear out the sprockets and/or the chain itself prematurely, as well as be noisy in the primary. There's NOTHING good about a too-tight primary chain.
In fact, there is a H-D tech bulletin about how to address a too-loose primary chain... this bulletin states to do exactly what I said above... accelerate quickly to a high RPM, then decelerate quickly using only engine compression... to allow the tensioner to ratchet up and tighten the chain.
SO... H-D's own tech bulletin to deal with a too-loose primary chain can actually PRODUCE the over-tight primary chain problem! The Hayden M6 tensioner doesn't have this problem at all, as it constantly adjusts via the internal springs to keep the chain at the proper tension at all times.
