Warmed-up a little today, so back into this. Double-checked the indicator, it's fine. But, neglected to do the finishing touches on the indicator holder, like tighten the nipple fitting, true/square the mount base, and re-clearance the inside. Re-ran the configurations and got new values, all a little off from the original. Of course, there should be some difference because these new tests were done with the reworked clutch pushrod ends, adjuster screw tip, and casecover entry hole. However, I feel more confident in these new values because of the alignment and stability of this new indicator holder versus my feeble attempts to get reliable/repeatable readings using a hand-held caliper depth guage.
Revised summary of the mods to date:
Configuration #1 - Stock XS1 worm, 1.3" clevis hole distance
Configuration #2 - Arm bent down 0.4", 1.3" clevis hole distance
Configuration #3 - Arm bent down 0.5", 1.7" clevis hole distance
Configuration #4 - Same as configuration #3, modified cable/elbow entry angle
#1: Pull-test = 25 lbs, Actuator travel = 0.062", Cable tension = 150 lbs
#2: Pull-test = 18 lbs, Actuator travel = 0.064", Cable tension = 108 lbs
#3: Pull-test = 14 lbs, Actuator travel = 0.046", Cable tension = 84 lbs
#4: Pull-test = 13 lbs, Actuator travel = 0.051", Cable tension = 78 lbs
