I have 1800 miles on my clutchmasters stage 3. In the last 2 weeks my clutch has stuck in the fully disengaged position for about 1 second when doing high rpm (7-8K) shifting between 2-3 and 3-4. Any explanition? During all other driving I have never had an issue.

 

I'd say it's a hydraulic problem, not the clutch itself. Bleed it and see what happens?

 

maybe your master cylinder is giving up on u...
