Hopefully this is an inspiration piece for those who are still dialing in their machines or contemplating a purchase.
Many thanks to the people who have posted info and instructions about this game! Extra thanks to chuckwurt for answering so many of these forum questions!
I finally tackled a list of small changes and it made a huge difference! Adjusted the following: TK lock arm out and down per the Stern instructions, right flipper tolerance was too tight, dialed in playfield angle with a digital gauge (needed just a little more than the centered bubble gauge to get 6.5), "motivated" left lane gate where the ball would get stuck, moved a UV wire that created a shadow under the apron, aligned opto under the Demo, focused projector, moved outlane posts, and realigned targets.
Took about 2 hours of a lazy evening to address all but one item on my list with the most difficult part being not having small standard size tools as my toolbox is almost entirely metric for cars & trucks.
I'd call it a success as within a dozen games we had, two MXV skill shots, second ever Total Isolation, new high scores, and the wife got her first TK multiball. It feels like a different machine. I would say TK locks are ~80% and if they don't stick, the diverter moves and the ball makes it to the post vs. rolling back and SDTM.
Prior to this, all I had done to this pin was clean it at ~700 plays, added a hint of wax, and rotated the flipper rubber. That alone sped up the game significantly, made Demo shots even easier, and increased our TK lock success, but the TK fails STDM were still frustrating to the point an adjustment had to be done. As for moving the outlane posts, we still get a lot of balls through there so I don't know how much that little adjustment really helped. If anything since our guests are not pinheads, it makes them just a little more happy to play just a little bit longer.
Now to fiddle with a hyperloop...
