Setting Up My 06 SB Gearing/Clutching

Not sure on yr gearing since I mainly ride deep mountain..

As for the secondary spring, I would go stiffer then the red/black spring...at a minimum i would go red/pink...otherwise I would do black/white as my #1

As for the helix, you have the numbers correct, but NOT that one in the link, that is NOT an ER..(electronic reverse) make sure you get one that has ER after the number or you will not be backing up your sled

Good luck

Don't mean to hijack your thread but I guess one like this one won't work with reverse either?

I thought the E stood for electronic reverse, didn't know it had to be ER.

My setup for UPofMI, and WI:

10-76
Polaris Blue 120 - 300

66-44-42
TEAM Red/Black 140 - 240

115 Belt

24/40 gearing

Tach recall is 7800, I can watch 7700 - 7750 as I accelerate.

A few things:
I didn't like the TEAM Black/White, as it raised trail/cruising RPM too much. Top speed with the Black/White setup was 109, and top speed of the Red/Black setup was 103...this tells me the belt may be slipping at higher speeds. I have no experience with the TEAM Red/Pink, but this may be a very good spring to play around with. When doing some serious boondocking, when reversing, my secondary sucks into the forward track on the 420719 helix. You may be able to have the reverse track machined out a little bit more... I think danduvall did this.

I'd like to try some 10-78's for my max RPM issue, and maybe go back to the Polaris Blue/White(120/310) primary spring... Eventually, I'd like to start playing around with the 11 series weights, they were designed for the high torque Polaris engines. The only issue is that the primary needs to be shimmed for the 11 series, as they have a "fatter" low-engagement profile.

I hope this helps!!!

This is what im running flatland trail riding on my 06 fusion 144

mtx 78 grams
black/green spring

66/44/46 helix
red /pink spring next will be black/white
derlin washers

stock fusion gears
819 belt

and im running around 7800 hard to the bar ,works the best of anything ive tried so far!

Thanks! Thats all good information.

I think finding the helix is going to be the hard part.... Would really like to find a good used one.
