What kind of chain tensior does this bike have and if putting the Hayden M6BT07 primary chain tensioner help
I have a 2013 cvo road king
Your bike has the stock POS Harley ratcheting primary chain tensioner. This tensioner ratchets up to tighten the chain, and then stays there. It will not come back down. This can, and often does, lead to over tightening of the primary chain.
An overly-tight primary chain puts stress on the primary bearing at the front, and on the transmission mainshaft bearing at the rear. I haven't seen any research documenting increased compensator wear from an over-tight primary chain... but my gut tells me that an overly-tight chain would seem to put stress on everything in the primary drive - including the compensator.
The Hayden BT07 is a spring-loaded tensioner that keeps the primary chain adjusted properly, and continually adjusts the chain tension via the springs. I have it on my bike, and I had in it my previous '95 E-Glide too.
I really like the Hayden. It's much better than the stock Harley ratcheting tensioner. The primary runs more smoothly, and doesn't clunk nearly as much when shifting. When I'm out riding with friends who still have the stock ratcheting tensioner, I can clearly hear them shift from neutral into first, even over the loud exhausts... and some of their bikes will even lurch a bit. My bike just clicks into first quietly.
Running a good gear lube such as Red Line Shockproof or a good 75W-135 or -145 gear lube in the tranny will quiet things down and make things run more smoothly, as well. I run the Red Line Shockproof in the tranny currently.
As someone else said - it's important to NOT overfill the primary. The fluid should just come up to the bottom of the clutch basket. It's only in there to cool the wet clutch and prevent the primary chain and sprockets from rusting. Too much primary oil can cause the clutch to drag when the lever is fully pulled in.
