P.S. After a sleepless night I solved my problem: I removed the port side (left) locking bracket from the seat, thereby functionally eliminating the left latch. Having two latches cable-controlled by one switch is a design mistake, something I learned from years of trying keep Model A Ford brakes adjusted. Why two latches, any way? If one is good, two must be better, right?
Now to get my hands on the designer of that saddle. He needs to be sterilized, at the very least.
If not for this forum, I'd be riding and wrenching on Hondas or Yamahas. Thanks for all your help, guys, it is appreciated.
