LOL, I tend to go on and on sometimes Jim. I was out in the garage just now having a smoke and I recalled your comment on wanting a leading link, or Earles front end.
I had a vintage production "Trail Tamer" front end, which was a after market deal offered in the 70's, to make your Taco mini bike more offroad friendly. I had one on my Taco 99. Decent little engine on it, five inch wheels, and at about 40 MPH, it would start to shake at the front end.
Using the standard measuring procedures of getting the fork geometry, I can only "assume" it would be the centered effect of the front shock and actual fork. Using that, with the vertical plane, it's easy to see that the trail would have been very close to zero, if not slightly positive. But as you said, at low speed, the suspension did just fine, and worked well over terrain.
