Good afternoon Gents -triton28 wrote:One of 2 things comes to mind: first the forward smaller hole in the bottom of the master cylinder may have some corrosion building up and restricting the return flow of hydraulic fluid thereby causing the clutch plates to remain disengaged; or second, the slave cylinder may have corrosion preventing the piston from returning into the bore of the cylinder.
The first can be cleaned with a strand from a wire brush, and the second is a little more involved in that the slave cylinder must be removed and visually inspected.
Hydraulic brake fluid absorbs air and as such the moisture contained in the air reacts with the aluminium to form crusty corosion. It should be changed out each and every 2 year time period.

I have a '91 Voyager XII. Several weeks ago I began to experience clutch slippage. NOT a welcome problem!
After doing quite a bit of reading on this forum, I decided start with the master cylinder. The fluid was indeed cruddy, and after I got it all out, it became obvious that the tiny return hole was plugged. After cleaning it out with a wire brush strand, wiping everything down good refilling it with new fluid, everything seems to be working perfectly.
I'll add more, later, if I encounter any more problems.
Thanks for the wealth of information!
Maybe measure the clutch springs. They may be at the service limit but are easy and cheap to replace.
