Clutch release mechanism

[Rasputin]

This may be of interest, or you may already be aware.
While attempting to repair the alternator stator on my TX750, I had the LH case off and decided to clean and lubricate the clutch release mechanism. Thinking it would be a steel benbix in a plastic/nylon bearing, I was pleasantly surprised to find ball bearings inside, see pictures.
I am not sure which type the XS/TX650 has, but you have to admit that this type is better, I think.

Yes, that *IS* very interesting!
Yamaha TX750 ball screw assembly 341-16390-00
Unfortunately, it rotates in the opposite direction of our XS650 actuator.
But, I bought one anyway. You know, for research.
This eBay vendor in Texas has a bunch of these, NOS, $18.

Silly me, of course the cables come in from opposite directions. Doh.
That shoots my master plan out of the water.

I've often wondered why yamaha chose to use a nylon and steel combo . I guess I assumed that they went that route to prevent friction or seizing of the worm due to rusting or thermal expansion.

Yeah I like the ball ramp style as seen on many Hondas.
