This is scary guys, because if the problem is in the clutch housing, I may have to bury the bike.
Whoa cowboy, don't be thinking terminal just yet.
Is there a bunch of play in your lever? The lever could also be the reason. I'd a thought your mechanic that bleed the system would have checked that out. There should be a brass insert in the lever where the pivot bolt goes through. If it's missing or deformed, I would buy a new lever (OEM $12 or so)
So for cheap money and easy work, replace the lever and bushing. If you really want to rule out the lever being the culprit, you could also replace the pivot bolt, rod and boot.
Even if it's in the clutch and not the lever, master cylinder or slave, it's not a LARGE expense to fix. Depending what is wrong, should be under $500, I would think.
I'm surprised no one's come forward in your area to help yet, but maybe post something in the TX board.
