One afternoon I decided to "tinker" with the altitude adjustment clamp
on my Etx-125. I noticed that the clutch clamping action was applied to
the right fork bearing with a small steel thrust bushing about 5/8
inches diameter.

I dropped the small 5/8 inch bushing and replaced it with a 1&1/2 inch
diameter x 1/8 inch thick nylon washer with a 1/2 inch center hole. I
then tapered or "re-leaved" the 1/2 inch center of the nylon washer, (on
the inner or telescope side) so it would slide more easily over the
plastic center where the adjusting knob screws in.

Then I lubricated both sides of the new nylon thrust bushing wit a very
small amount automotive synthetic di-electric grease, lithium grease
seems to react with the aluminum on the right "false setting circle
disk.

Clamping action seems much improved.
