Is a single break in a friction plate a major crisis? This happens to be on a CB200T, but its the same part number as "friction disk B" on a CB400F.
My belief is since it is fully contained by the outer clutch basket, and I place it in the position that has the "least movement" when the clutch is disengaged, it oughta sit there and do its job until I can get a new plate.
