A worn clutch is unserviceable because the plates are out of specification what we are
talking about is normal glazing and contaminates which is not oil related... All you have
to do is invest is some good old sweat equity to cure the problem...
Deglazing clutch plates ain't nothing new... no sir... back in the 70s
it use to be part of every savvy rider's maintenance plan... and for
some reason that all change during the 90s... why fix what you can buy
new is the what you hear now a days... but if your interested in
making your clutch bite good as new then roll up your sleeves and read
on... if not get back on the couch...
Inspect the friction plates for glazing... make sure you have plenty
of material to work with... your shop manual states clutch thickness
in thousands of an inch or mm...
First removed the contaminants with Acetone... pick a hard surface to lay
over a 600 grit black dry emery paper... rotate the clutch plate in a
circle... you're just busting the glaze... don't get carried away
remove too much material... You should end up with a friction plate
looks dull like a new one as opposed to a shinny glazed one... recheck
thickness...
Next check the pressure plates for bluing caused by localized heat...
make sure they are not warped... consult the manual for a thickness
range... now removed the contaminants with Acetone and wire wheeled
them to erased the blue and also to generally scuff up the surface...
you should end up with a dull surface free of Blue marks...
