I travel a lot and as such only get to take the 90 out of the garage about once every 6 weeks. Every single time for the last 6 months I hop in and have no clutch. I pop the hood and look in the clutch fluid reservoir and it's bone dry. I add a bunch of fluid and bleed it and all's good for the weekend.
The weird part is there's never a puddle on the floor of the garage. No drips anywhere. Nothing. It's just gone. The drain plug isn't in the bell housing so it's not in there. I'm at a loss. I can fill and bleed the system in about 3 minutes now from all the practice. It's getting old.
