The issues they had were more than a little blip in the production timeline...

I bought the Hayden when they first came out with one for my bike. I had read about the problems with the HD auto tensioner and wanted to stay ahead of the curve. I procrastinated on installing it for no other reason than laziness.... I was glad I did...

Their instructions were off about the gap for set up, and along with the older, taller springs, that led to several forum posts of people who had banjo-tight primary chains with the Hayden...... It took awhile for them to admit an issue, and then come up with the new springs.

I had the original springs and after reading about the problems and finally a fix, I contacted Hayden. They did send me the newer spring set....

However, during that time, I learned that the MoCo had updated the auto tensioner. In 2009 it was #39929-06A and in 2010 it was changed to the #39929-06B. I saw pics of both, side by side. The differences were obvious and seemed to address the over tightening.

Since my bike had the newer design, I left the OEM part alone and have had no trouble... thus now no need for the Hayden..

Hayden originally put a product to market that they apparently didn't do much testing with... just went on past success, designs.... in it's original version, it wasn't very good... and caused the problem people bought it to address...

 

The shoe edges don't collapse. The shoes tabs that the metal u runs between wear or crack.

 

 

Set to specs I have Hayden in 4 other harleys ( twin cam bikes) My first Hayden in a M8. Hayden said it looks good button it up and enjoy the ride. Then I sent them this pix and now they are sending me a new shoe. Im going with Baker!!! 4200 miles??? now I will say I have had zero issues with the pads they give you for twin cam bikes

 

Nothing wrong with the stock tensioner. I have an 07 EGC with 104000 miles on the stock tensioner and a 17 RK with 40000. No issues. Just replaced a primary chain, comp and tensioner on a 12 RG with 102000 miles on it.. Tensioner was worn but still functioning.

Your shoe has micro-fracturing from bouncing up and down.

 

I took a stock one and welded it to keep it from ratchetting tight. Check it every 10k still havent needed to grind the welds off and moving it up yet 40k on it. I just kept reading about the comp issue on the twin cams and thought it might be caused by the over tighting of the primary.

 

F*K reallY? I literally just put this in, have about 2500 miles on it and all it does it knock. But only after it warms up! !

 

I have had the same Baker since 2012 in 2 bikes with no problems so far.

 

I installed the Hayden in my 14 trike without the shims, it knocked a bit so today I added both shims and it is now way quieter. It seems to behave move like tne one in my 07 flhtc. Will see. I did switch to Formula plus as well

 

I run a Hayden in my old Evo without any problems for years. Shifting is smoth and the "Clonk" is gone. Would buy it again and again.
