Clutching for Cooke City, Mt

[jtt454]

I was wondering if I could get buy with arctic cats clutching st up for 6k to 9k? or should I by the weights for 9k plus?

Majority of riding is 85-9500. I would do the 9,000 setup. I am not much help because I run the SLP pipe, so I run more rpm's.

spend the 60 bucks on the proper clutching and u will have way more fun. 2 stroke don't like being out of there proper rpm range. 7700 is optimum for full h.p. in the m-8's. Have fun in cooke!

m7 - 65-66g (stocker)
m8 - 67-69 (with mods)
m10 - 70+ (with mods)
or get a set of 65g cutlers and adjust as needed.

If it is stock than just install some 70G weights and you will be good to go.

i ran with my 6-9000 weights at cooke last year without any problems what so ever. i have some 9000+ i am trying this year. hope to get a little more out of her.

Thanks alot for the input, think I'm going to get the 9k plus weights so its running the proper rpm.

Don't install the 68G weight if your not running a pipe, they are to light. The 70's work better and pull harder.

first of all what sled are you running 7 8 1000 cant tell you if we do not know

Sorry stock 08 XF 8 SP just have MBRP can with 2" challanger

I would say 68s with spring adjuster in secondary turned in .5 inch

The 07 and 08 sleds do not have spring adjusters from the factory, so there is now way to adjust them.

I have an 07 Crossfire 800. I run cutler adjustable weights and load them with about 70g all as close to the heel as I can. I also run the gold spring in the Primary and the stock orange in the secondary. I have switched between the the recomended 36 degree and stock 46-40 helix and depending on snow conditions I prefer the stock unit. This with a 136" 1.75 track.
