Hey thanks for the replies so far. This 3-wheeler is a 2014, #6 of 50 Brooklands edition. First owner had only 628 miles on it when I purchased in April 2023. At about 947 miles I had to get the exhaust TIG welded back together o the right side, along with flex joints and new bobbins. Over 1200 miles since that event. Currently just about 2200 miles on it. The clutch never slipped, even yesterday when I had this breakdown. I grew up driving manual transmission vehicles so I never ride the clutch so my hope is not having to pull the engine. It was hard to disengage twice, but acted normally for a couple of miles and then when I finally pulled over at a petro/food stop she wouldn't disengage without braking and stalling the engine.
She's on jack stands so I can inspect underneath. No fluid leaks noticed in a brief inspection so far. Today I will look closer at the pedal box for leaks and try to bleed the system.
