Hi folks,
I've been doing some reading in preparation for de-glazing the clutch on one of my scoots.
Last time I did this I just lightly sanded the drum and the pads, but have read that apparently Boric Acid helps, & maybe cures this?
Anybody here use it?
If so:
How & where did you apply it?
Did you still sand the pads and bell?
If ya didn't sand the pads and bell how long did it take before everything de-glazed?
Thanks in advance

Glazing is a hot polish that's put on the clutch pads after sustained slipping,,, sand the pads with 120 grit sandpaper and the bell inside and forgo the boric acid and any other kind of remedies,,, slow take offs are to blame here,,, get the scoot going and rip the throttle wide open so there's minimal slip,,, riding technic is the culprit here

boric acid would be the last thing i put on a friction surface.
boric acid could probably substitute for graphite, it makes things pretty slippery.

As long as the inside of the bell is clean metal it does not matter. If it's smooth as glass that means the pads will last longer.
However the pads need to be cleaned sometimes they can get sticky and won't slide without shuddering
Slipping is beneficial it allows the motor to maintain higher RPM on launch. Too much grab can be a problem my 250 had a hard time with launch it would shudder and grab.
The solution was a couple drops of 80W90 inside the clutch
Worked fantastically after that
If you are concerned about the clutch slipping at speed
You can be assured this is just not a problem with a centrifugal clutch any faster than 15 to 20 mph and the clutch behaves as if it was welded together.
It is completely locked until the bell explodes from excessive centrifugal force
Wouldn't that be fun 😱

as stated this could be from slow take offs but it can also be from too high an idle rpm. with the scoot on the center stand if the wheel turns even the slightest at idle it is too high and will continue to glaze the the pads at all stand still moments.
