Cb750k6 clutch disc query

Paulreade:
I received a post back from the us site today stating the complete opposite - they referred to a tech bulletin which I have asked for a copy.
It's a lack of confidence issue I guess trig, plus a habit of a working lifetime of clarifying everything with all and sundry before work proceeds. Its  all a bit confusing to someone who has never delved into a motorcycle engine before and wants to ensure the bike is preserved for years to come.

K2-K6:
I think there's information that leads to conflicting opinion on this.

The Honda manual I have for 750 F2 is very specific in stating that the angled slot plate should be fitted as picture B in your early post.  it also has the double plate fitted to centre clutch pack.

As far as I'm aware the angle is there to manage oil dissipation as the clutch is released and so will affect the bite "feel" and how smooth the initial drive takeup is. It doesn't look like it will cause a problem as such when fitted either way, but it should change the operation in a small way but only for pulling away from a standstill.

If you look at how the clutch operates,  engine running,  clutch open, in first gear.  Then the metal places are stationary with the fibre plates rotating with the crank, and oil between each interlayer.
As you bring the clutch toward closing then it has to squeegee the oil out of the layers to gain traction and start to rotate the metal plates. This is then driving torque through the gearbox.

As the plate with the angle slots is approached by the flat plates either side of it, the oil has to be wiped into the slot for its exit route out of the clutch pack. If the slots face forward (as in A) then it has the effect of working against centrifuge, which keeps the oil in play longer, which gives a softer clutch bite. 
In the B plate scenario,  the oil is less retained against centrifuge,  so should give a quicker bite transition,  and potentially more difficult to modulate torque takeup.

They both don't seem technically wrong but should give subtly different initial affects.

I doubt that the affect is aimed at moving geachanges as all of the clutch pack is moving together after initial pull away. 

If you don't like the effect when installed, then it's easy to flip the plate.  It's more fine tuning by designers than any technical disaster if it's fitted backward.

I have always fitted them by the Honda manual, which is in the picture with the 500 four clutch and states " NOTE, Fig 118 "  ;)

Paulreade:
Good answer to the question. I will fit as fig A. Keeps everyone happy and makes sense.
Really appreciate the input.
Many thanks
Paul :)

Trigger:
The other concern is 6 of your plates should be "C" vertical so, it will be interesting to see what the result are as, i have only fitted 6 vertical and 1 angled to a K6  ;)
