I've got an Attack 20, 1.7" X 129 with a 3.0 pitch and am looking for set up tips for out west powder riding. I will be using my stock 1" for the flatlands. Just wondering if anybody is using this set up. I believe I need to run the 8" extrovert drivers, but am wondering which clutching and gearing to use? :beerchug: :fluffy: Thanks!!

19/40 gearing if you go with the same size drivers. Put it in hill climb mode unless you are going right after a huge storm. Take your snowflap off too.

Start with a straight 55/53 helix and a stock red/white secondary spring.
68 gram weights and yellow green primary spring.

19/40T gears with your 3" 8 tooth sould get you what you need!

I am not using this set up this is what I would put into a F7 with that track in the 3000+

redF7sp might have a nother set up too.....

On the 04's all you need to change is the weights, 63 g for 5K+ will be fine. A/C's clutching specs were spot on I thought. If you go with smaller drivers you might not need to reclutch at all since you've got the sno-pro already.

Where are you going?

Thanks guys!! :beerchug: My buddies have been running out in the Bighorns, Wyoming. I am hoping to tag a long and see what this thing can do out west! I have heard that with a good set up, the F7 can do pretty well. I got a deal on the track at Haydays, and couldn't pass it up. I have been toying with the idea of a paddle track for a while anyway. My only concern is about the 3" pitch. I didn't know if the stock Cat high altitude set ups would get me in the ballpark or not with the 8" drivers?!! :cn:

Yes it will.....the stock moutain cat 800 had 10 tooth 2.52"er and the 19/40 gear.

10 X 2.52 is 25.2 divided by 3" is 8.4 tooth. So your 8 tooth 3" pitch will have a lower gear than the 800 moutain had. That is what the 700 needs in the ups.

You need 8 tooth drivers, not 8" diameter. You definately need to get another driveshaft setup for the 3" if you plan on swapping back and forth. You can use any other non-DD F-Cat driveshaft to put the 3" drivers on. The Cat drivers might be kinda pricey- try Western Powersports or HPE instead. Be aware that Cat says the Sno Pro track vibrates alot at higher speeds- I haven't ridden an '05, so I can't verify that.

The 8T 3" pitch drivers are less than 1/2" bigger than the 9T 2.52" pitch drivers, so use specs for the stock setup at whatever altitude. We set my buddies' 03 F7 SP up with Cat's recommended weights, stock pri spring, 53* helix, and green sec spring for max backshift.

The bighorns are a lot of fun. Any idea when you are headed out there?

Not sure yet. Depends on my schedule, but I think they usually take at least two road trips out there. One early in Jan, and the other later in March. How about you? :fluffy:

 

[bluebear]

We usually head out there mid march. Last year they got 3+ feet of fresh snow while were were there. :fluffy"

Looked like High Performance Engineering had some decent prices on 8 tooth drivers, and will scout around for a new drive shaft so I can swap out when heading out west. This site is great. I DO appreciate ALL of the help and suggestions! Think snow!!!! :banana: :fluffy:

That is exactly what I needed to hear! Your making me drool!! Seems like it might be worth the hassle and expense to do this. With the lack of snow around here locally.... No wonder the Crossfire is selling like crazy. Going to stick with my F7 for now. Hardly broke in yet..... :beerchug:
