[Supras] New clutch slipping, shifting problem?

[Walker, Brian (Rich. Dist)]

Didn't put much, I think it was due to a poor shift at the beginning of
the lap. I wasn't sure if that would allow it to slip but evidently it
can. I'll be trying it out under full sessions next month (these were
time trial laps from a stop) and will try to smooth out the shifts by
then.
 
Btw, does the press. plate normally change the engagement point
drastically? The pedal has to be depressed almost to the floor now and
we've bled it a couple of times.
Thanks,
Brian

Could have glazed in the bad earlier shift...doesnt have much time on it
either.

It SHOULD work itself out...over time.

If it doesnt..its nothing that 200grit sandpaper can work out, but we
all know what that would take to do.
