Have to imagine at some point everything will be going to that.

What about the belt? Can't remember if the P22is the same taper as the P85/same belt between them ?

Same belt, not sure on clutch angle.

Is the P22 a good one?, I have not heard anything bad about it in general. I personally have been so happy with clutches on the 800-850s, it has never been any belt issue and easy to tune. Question is if its a fix of something that is not broken??

The clutch wizards can get into detail whats wrong with the p22, what i like about it is the belt life, it seams very good.

The problem is that you have no way to set belt deflection on the machines with the P 22 as the secondary has no way to set it!, Just the way that I see it,

That is kind of the point with the P 22 and the roller bearing. The belt deflection is always as tight as it can be, thus removing the need to manually set your belt deflection.

So, your belt never wears?

No, your belt will still wear out and eventually need to be replaced. With the P 22, your belt will always be tight against the roller bearing in the primary and your belt will come to rest, tightly, in the secondary. You do not need to set the position at which the belt will be at in the secondary like you did on the old style clutch as the belt wore down/stretched/broke in.

It is the same secondary clutch. They just removed the belt deflection set screw.

As the belt wears the secondary will just close more keeping the belt tight. Cat has been using this set up since 2017 on 4 strokes and 2018 on 2 strokes. It performs great.

Back in the 70s when we were running Comet clutches, I put roller bearings on the primary after disassembly and a little lathe work , this helped with belt wear and and cleaned up engagement issues at that time and with a little machine work on the secondary, we were in better shape . Things seem to come full circle and there seems to always be improvements on the new ideas as we get there!!
