As for the topic part I have no idea if they are worth the money (add power as claimed) or if they will hold up over time so I abstain, no opinion.
We will know in a year. No bias to speak of about the company but I will let others learn about them before I dive in.
The Baker chain tensioner puts the bike back to the point (Pre 07) so that the auto tensioner is not over-tightening the chain , a problem which is exaggerated by a hi-performance motor.

well, i'm pretty sure my tensioner is in need of replacement at 39k (assuming mine is hydraulic), fibers are showing up in my filter and i've developed a nasty sound once the bike warms up which changes with oil pressure.  thought the new harley tensioners were good for 50k or more which makes me wonder my 09 is the old spring-load. i'm on the fence about putting installing this tensioner, my experience with zippers wasn't all that great either.  either way, a new pump sounds like it is in order.

 bikes up and running now we are runing over 50 psi oil pressure with the zipper and baisley spring and valve   
   is this pressure causeing a new problem of  oil burning and failing plugs with oil
did a compresssion test both cylinders 150 psi after a 30 minutes down about 135 rings ? or to much oil presure??
500 miles on motor exhaust oil up

extra oil pressure can cause all kinds of problems

we all know about "if some is good more is better" but its not true

Certainly if bleed is slowed in one place and pressure is raised this changes the oil distribution (balance) in the motor, piston jets come to mind as a producer of higher quantity of oil plus with that much pressure they will be active all the time and never shut down as they were designed to do at idle <14psi, for one plus the quantity of sump oil generated.

Regarding the oil consumption, first find why the compression is low. This is a separate issue but not necessarily unrelated. Assuming you had the throttle wide open when the compression was tested.

Disclaimer: I still have no opinion about the tensioners and have had nothing but decent dealings with Zippers.

throttle wide open on cmpression test new to harley building tell me more did it old shool  installed gauge crank  got to hidhest point stoped checked for bleed done??

You should hold the throttle wide open when performing a compression test...

did not know that thank you

With an electronic throttle, you will need to block the actual throttle plate open, not just hold the grip wide open.

You will see ~25 lbs more IME

thanks iam old school this new sh*t still learning

What about ACR's do they figure in whiledoing compression test?

I think you already know the answer to your question ... ... but for those who might not know...the ACR's need to be disabled (I simply unplug them...).

You have to stick your tongue in through the spark plug hole and let it cover the ACR hole.  Some guys can do it with something other than their tongue.  But I'd never admit to that if I were one of them.
