This is my third thread on breaking in a new AXYS/Matrix sled. 2015, 2019, and now 2023.
I'll check all critical aspects of the new sled and post them as they get checked. Get ready to become more knowledgeable, along with me, on this new technology.

1st order of business is studding.
My track is the 1" x 15 x 129 Ripsaw 2 R high performance.
Plan to install Woody's Trigger studs in double backers.
Tunnel protection TBD.

In reading the owners manual:
The primary clutch weights are 14-84 grams, Spring is a 165-310.
The secondary has a 58/44 .36 helix and a 155-222 spring.
Chaincase gearing is 23/37. 68 pitch chain.
Drivebelt is 3212325.
Belt has same dimensions as the 1215 made for the NA 850.
Center to center for clutches is same as NA 850 at 10.625".

You sure the belt is dimensionally the same as the NA 850? I don't think it is....

That's what I thought was written somewhere. Might be wrong info. I found it in a different location. Not the owners manual. The only thing not the same is the belt compound material used. Same Outer Circumference, same face angle (28deg), same width. I'll measure my own belt to be sure in a few days. What is your understanding?

My guess is center of drive clutch is larger in diameter because of bearing.

So, everything the same except Circumference 45.51 for Boost and 45.16 for NA 850. .35" more.
This can be because it's a slightly longer cord length or maybe a thicker belt above the cord.. I'll roll it on a table to find out.

TJ @ PatrickCustomCarbon is pointing out that these deflection screw/nut free secondary's are out of balance (more so than usual) without the screw. I'm wondering if Polaris realized this late and that may be the reasoning for the "bulletin" about adding the screw for those experiencing track creep. Just a donkey brain idea/theory shrug.

Correct. Almost 3/8" larger OD. One of the reasons I'm going back to a P85 on my boost.
I doubt that it will be much different. The deflection that you need with the P-- 85 probably is about the same starting ratio as the P-22 with no deflection. Some of my measurements will be to compare secondary diameters, forward twist of the engine, and c-c of clutches.

Those are SLP magnum force weights. these work very well. Already had these on the snow in M.E. they act kind of like tucking the weight. Allows the turbo to spool up about the same time as it shifts. The result is 0 lag. The 14 series weights are wider where the weight pin is .910 wide with bushings that look like a-arm bushings, but a lip on each side. Stock 10 series are .465 at the pin area.
