Metal clutch plate

Need to know if there is a correct way to install the metal plates. One side has a round edge and the other side is not.
I check another engine I have and the plates are the opposite.
So which way do they go...round edge out or in or does it even matter?

i say it don't matter.
the surface of the plate and the face of the splines is all that contacts anything.

I'm not 100% sure myself. 99% sure though.
Considering that the driven friction plates rub, slip or lockup on either side of the steel plates at all times when the engine is running, does it matter at all?
The only time they aren't locked up is when you pull the clutch lever in.
So, I don't think so.

I was wondering the same thing a while back and asked Jeff at Z1 ......... he was out and took a couple of days to get back to me so I installed em sharp side in thinking it has a tiny bit more surface and might bite harder.

He got back to me and told me it really is no big deal but curved side "might" engage a little smoother and the main thing was to keep them all the same...... I have them out again as I just replaced my starter clutch and will probably put em back sharp side in as they felt good for the first 400 miles after I replaced em.

Trying hard not to LOL!
That wouldn't make any real difference.... it just means that the friction plate at the start of the clutch pack housing or the one at the end near the spring plate would see the final smooth edge.
Honestly, although fun to talk about stuff like this, I think that whole idea of front and back is just silly and you can randomly put them any way you want with ZERO effect.
I bet the sharp and smooth edge is an artifact of stamping out the plate and nothing more.
You have more of a chance of sensing the clutch feels different by chamfering and smoothing the inside of the clutch housing basket slots where the tabs of the friction plates move slight;y back on forth during lock up and release.

Cool....we all know now...lol
