OR.. trueing up the t.o. bearing surfaces on the release fork. I read
this on this list in about 1999. Done it many times since. Don't waste
your money refinishing the flywheel. Put in a new release fork or spend
a half hour with a grinder and a caliper and spend some quality time by
your bellhousing making the fork surfaces smooth and exactly the same
height. Without being uniform, the pressure plate will throb as the
untrue bearing lifts it. Doesn't take a rocket scientist to take it from
there.
