OP here.
Well from the 10 post this Thread has got so far looks like the main reason to install one is to help the IPB from going bad. 'dawg' and 'jayStronghawk' felt some improvement in how the primary works. But '05LowRider' 'lionsm13' and NEcaveman' felt little or no improvement in the primary. The reason I'm interested in this is my 11 King with 17000 miles has a wiring sound from the primary and I get a very loud clunk from neutral to first, a lot louder then my last 3 Harleys. I get a lot of clonking that sounds like chain slap but the dealer's say it's just the compensator.
I live in Michigan and it won't be long and she will be put up for the winter and my Warranty runs out this December.
We all know that sometimes on this Forum, a lot of people go buy a item just because every one seems to be buying one, I don't have the $ to waist on the next new thing.
I hope to hear more that it will make the primary work smoother and quieter and not just because it "might" help the IPB.

If you use an online oil viscosity calculator for bearings (typ. SKF) you will obtain the required viscosity at a given temperature under normal load of the IPB.
At 150 Deg Celsius the 5207 calls for a viscosity ~8 [mm^2/sec] (HTHS)
At 100C it's ~15
At 40C it's ~150*
*edit= (150 is the equivalent viscosity at 40C meaning a grade 40-50 oil will still be efficient when reaching 150C)
From these values you can evaluate your driving habits and see where you stand. Formula+ is perfect for people "in the middle" of a sample, like you and me [today]

I live here in the Smoky Mountains, 90% of my riding is on twisty roads and most of the time I'm in 2nd or 3rd gear using a lot of engine braking, I can't to see how that small spring on the Hayden will keep tension on the upper portion of the primary chain when using the engine to slow down a 900 lbs + of bike and rider. That upper chain must be slapping the primary top.

My complaint with the stock system is it either takes up too much slack tightening the chain or the teeth slip allowing the tensioner to unadjust causing the chain to flop around.
I've had the Hayden on for a few thousand miles and recently removed the outer primary housing to inspect the tensioner. I found no evidence of the primary chain making contact with any part of the housing.
I can report I've spent quite a bit of time in the north Ga, Tn, and the Carolina hills (as well as the nice hills here in New England) using the Hayden system. And, like you, I use engine braking for many of those rides...so far, so good.
