A bit slow getting back to this, but I had to order a new O-ring from the dealer (ridiculously priced at $10 as it is a pair in a set, but you only need the larger one and not the smaller that goes on the black unit's plunger) as I wanted a fresh one in when I pulled the 3rd Gen. tensioner off the K1200GT (the black hydraulic cylinder one mentioned.).
The "Beta" one that APE gave me for a trial fit worked well, although I have to get back to them on the measurements for the bore and first and second bore fitment. Not a big issue to install and maybe 1 hour at most as I'm slow and I took a lot of photos too. I had only about 0.200" threads left before it hit bottom so that thread length may need to be a bit longer too.
No issue getting the old one off using a 1/4" swivel and an 1/4" 6-point socket on a hand driver. Some external Torx screw they use in there, but the small 1/4" socket did the job.
I ran the screw down until it bottomed out by hand, then wrenched in an additional 1/8 turn. Put the bike in 6th gear, and rotated the tire back-and-forth to get any more slop out of the cam chain. Then backed the adjuster off, and hand-screwed it down tight again, added 1/8 turn, and then backed it off 90 degrees.
Tightened up the lock nut (either a 5/8" or 16mm combo wrench will work) and fired the beast up. Absolutely NO cam chain noise at all on firing up, and no oil leak...yet.
I need to get all my measurements back to APE this week and see what they say. Their machinist was a bit worried about the dimensions of the upper bore for the bike and he has a lot more meat there he can deal with to make the device more rigid.
Fwiw:
I tried to post the photos of the unit and the install on the 2006 K1200GT (should be good for all K44 series engines: i.e. K1200/K1300), but seems I'm max'd out on what this site allows for photos.
