7 Tooth driver gear down. secondary clutching help

[r.c.rob]

I am installing a CE 163 on my 2013 pro 800 155.
I want to gear it down with a 7 tooth driver.
What is the best secondary spring and helix for this set up.
I am thinking it would be close to curts clutching with his gear down kit.
But i dont know what that is.
Thanks Rob

Stock Gear ratio is 2.09:1....

Drop in a 7 tooth, 2.86" pitch (stock-pitch) driver...

2.09/.88=2.375:1 FINAL DRIVE RATIO

Check with TRS on his Clutching setup for that gear ratio.... His stuff works IMO.

A CE is a 3 inch pitch not 2.86?

There's 2 versions of the 2.5" CE, a 3" pitch and 2.86". He's installing the 9105 track (old style 2.5 CE)

Yes I am installing the old style (with fingers) camo extreme 2.5" lug, part # 9105m.
center port 2.86" pitch single ply fully clipped.
Hoping TRS will chime in and let us know what he has come up for clutching on this track and 7 tooth driver.
Thanks Rob

Dose anybody know what secondary helix and spring curts Polaris uses with their gear down quick drive pulley kit?

The 7 tooth 2.86 drivers are the variable here. I can give you the set up we are running for a chaincase geared 19/46. It is a completely different setup than a stock belt drive/driver combo.

That would be great. it will get me close.
With the 7 tooth 2.86 drivers and stock quick drive my final raito is about 2.37
What final are you clutching to on the chain case set up.
Thanks Rob

This is an all inclusive package for a chaincase model with 19-46 gearing. 2.5" x 2.86 pitch track with 8 tooth drivers. 8-10,000'. You must use these parts, Lightning weights, springs, and helix. If you use a different weight vendor/profile, results may be less than desirable. The lightning weight, when lightened, must have each hole drilled equally.

Primary:
140-330 spring (stock)
60-62 gram TCP Lightning weights(elevation and rider weight dependent)
Clutch will need to be reshimmed for a .020-.030" belt sheave clearance.
If belt sheaves have been cut(Dan, Carl's, ect.) use a 120-310 primary spring.
Secondary:
46-32F ER Helix (46-34F ER other track)
Red/Green spring 120-220#
Blue/Black spring 120-200# (option)
This package was designed to work with the stock ....115 belt only. But I now highly recommend the Gates Carbon belt 44C4553.

Exhaust Valve springs:
Green/White Polaris part # 17041786-03
