Hey Bob, Sounds like you need a tad more clutch disengaugment. Whats happining is the input shaft is still turning, even with the clutch mashed to the floor. When it warms up, the tolerance between the disc and plate gets even closer.  Try adjusting the pin that pushes in on the slave to make it longer. You will know if you make it too long because it will not let the clutch  fully engauge.  I'm sure there is a more complex procedure but that is basicly it.  Well maybe. Bill 1362
