Sohotbikes wedge

There is a check-ball in the tip of the wedge, and the tube does fill with oil for some semblance of hydraulic damping. But without the spring, the wedge travels too far down the tube when riding the bike hard, and had a tendency to bind in my case.
No need for the wedge to be down that far and the added spring seems to have solved that. THEY should have included that spring. This item could not possibly have been tested much before going on sale.
But as you said, I "shouldn't have had to do anything except install it".
Correcto-mundo. It wasn't fair at all. No denying it and I ain't sticking up for Soho. I'm still pretty pissed at them.
Ive been running that POS revised stock auto adjuster for 16000 hard miles and not one bit of problem, but then again I dont fix problems that dont exist!

I got scars inside my inner primary from chain dragging across it. If it wasn't self adjusting, then what was it doing Einstien?
It's getting late, not gonna play with you all night.
G'nite. Unpleasant dreams.
Put the unit on, and after a bit over 140 miles was becoming concerned that there may be issues as others I trusted were having to attempt a fix and/or "blueprint" this new unit to work properly.
And I did not want to jeapordize the primary since a tensioner failure could result in a very expensive fix. So I pulled the unit and compared it very closely to the stock unit. After opening up the stock unit I found it's wedge was very different from the SOHOT wedge!
Stock unit:

And SOHOT wedge:

It definitely appears the stock wedge has a purpose built additional tensioning unit built in and after looking at the bottom of the shoe, I can see why it's designed that way. And by the way, the SOHOT shoe is an identical copy of the stock one.
What really surprised me after seeing the two wedges side by side, was I noticed a very strange wear pattern on the top and bottom of the SOHOT wedge!
Top:

And bottom:

As I've circled in the above two photos, there was a very small area of the SOHOT wedge that was contacting the shoe and the base. Appears the rear of the SOHOT wedge was actually "cocking" up off the base during operation and not being in full contact. Also, the hole in the piston were it attaches to the base is way oversize allowing the rear of the piston to foul against the base and not be able to swivel vertically.
I recommend anyone using this unit to carefully inspect it after some miles. As for me, I've tossed it in the junk pile and upgraded to the -06A factory unit.
IMO the SOHOT is a great idea, but the design and initial product was a disaster waiting to happen. Hope I'm wrong, but I can't afford the consequences if it fails inside the primary.

I didn't notice that type of wear on mine - but I can't say that I was looking for it either. Maybe I had some there, but I'd like to believe that it would have caught my eye.
Pictures don't lie.
Going into my primary was no big deal to me if I would have felt the SOHOT offering was going to offer so much more than the revised OEM one, but I never got the warm fuzzy feeling that it would, so I waited to hear from those that did get the SOHOT tensioner.
I'll be the first to admit, I may not be an engineer, but common sense does prevail with me sometimes....LOL.
Guess I'll stare at my crappy OEM compensator for a while too and just enjoy riding my bike
CLUNK!!! CLUNK!!!!
If yall need me, I'll be out in my shop taking inventory on what I'm going to fix that ain't broke.
Ben, how's that new motor treating you?!?!?! Axtell, eh? Niiiiiiiiiiiiiiice!!!!!
