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".

Great looking sled Patriot! I ordered the same color combo in a 137. I thought it would be rare to see one with black spindles and rails.

I have plans to add some enhancements to the graphics to make this sled be unique among Boost sleds. Stand by for lots more.

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?

What's a 14 series weight look like?

Not sure, but I'll find out.

I also went with black spindles and rails on my 137 VR1 Boost and thought the same thing as you! Lol

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

Correct. Almost 3/8" larger OD. One of the reasons I'm going back to a P85 on my boost.

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.

 

[patrioticinnovations]

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.

Here are your 14 series weights.

Looks like aftermarket stuff.

Looks like the heel clickers that have been around for years...

Not close. I run them in my 2000 XCR. The original fixed shoulder ones.

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.
