A guy I know just bought an '05 900 RMK 151". Has SLP pipe, airbox(not sure who's airbox), vents(again not sure who's). All updates are done. Rider is about 210 pounds or so, not a big hill climber or anything like that, just trail riding and some general off trail riding as well.
He would be riding at 1500 ft.(here in SD, flatlands), the Black Hills(4-7K feet) and possibly the Bighorn mountains as well(7-10K feet). I'm looking for clutching setups for these elevations. He's not much of a clutch guy so if possible something where he'd only have to change the weights would be a plus. As long as it doesn't blow belts and the performance is good, that's good enough, not looking to get every inch out of her.
Seems like the black/red and 66/44.46 helix are pretty much unanimous among 900 riders? What about the primary?
Is the 115 belt mandatory on these sleds or can you get by with the 080? I don't think he's gonna be happy when I tell him belts are $150 each.
Thanks

My '06 900-159 has the SLP single and reflash, SLP airbox and V-Force 3 reeds, as well as about 50 lbs. of weight removed. I ride between 4,000 - 7,000 feet.
My clutching is : Primary - 74g MTX weights with 2g rivet in the middle and 3g rivet in the tip - total of 79 grams, SLP black/yellow spring
(120-310 if I remember correctly).
Secondary - 70-42-.46 with Red/Pink spring.
Gearing was 19/42. With this setup, sled pulled very hard, but was still hitting the rev limiter (8050 rpm) quite often. I've regeared to 20/42 and hope to get out for a ride soon to try it out.

I am still trying to learn about this to see what I should be doing with the mods I have (a couple power adders I guess) and the Arctic Cat clutch ...
Right now I have my secondary set up just like everyone else, but the primary is set up just like you would for a stock 2003 King Cat 900 @ 8,000 feet ...
It works and is much peppier than stock, but I still feel like I have some tuning to do in the primary.
I have noticed I can't hold 7800 RPM a lot of times it seems to me it should be, but then again I really haven't had a lot of seat time latley ..
I think I finaly got all the kinks worked out of everything today
I'll let you all know how it goes.

I installed the 66-44 helix and red/pink spring. I changed my gearing to 19/42 last spring which made a big difference to. My belt stays way cooler as a result. Got into some deep powder yesterday and couldn't be happier with this set up.

What is your elevation, type of snow and your primary spring color? Just curious.

Glad its working out for you. After talking to Mountainhorse on this thread I got my buddies talked into going from the red/black spring to the red/pink spring on my old 900's, been working good so far.

Dogmeat, the stock spring is a red/black (I think) which is a 140/240. The red/pink is a 140/260. Same starting rate, but 20 lbs higher finish rate. Red/pink should give you a little better backshift and a little more belt pinch. Hopefully others with more clutching experience will chime in and correct me if I'm mistaken.
TTT,
good info..but looking at the helix's online and there is 2 different ones for the same angles..one for standard and one for LIGHTWEIGHT..
which would you get..is there a diff..
i have 05 900, tss-98..
ride at 6000-8000
will go for the red/pink spring..
have lightning 70 weights/Team Green spring in Primary..
also, i bought 18/40 gears but not sure if i should use them, or do 19/41..will stock chain work (dont know pitch of it)
inputs??

guido, the "lightweight" helix is for the TSS-04 secondary and the "standard" helix is for the TSS-98.
Can't help you out with the gear/chain combos as my manual is for an '06.

GKR,
Thank you for the help..i will install the 18/40 then..balance the primary and work on the secondary after i do that..
ANYONE HAVE INPUTS ON HEELCLICKER WIEGHTS for an 05 900???
i boutgh them cause they were a good deal, but i dont know if i want to machine the primary to use them??

Guido, one thing you need to keep in mind is that you should always go with the largest gears while trying to meet your gear ratio, more chain contacting the gear which increases the life of your gears and chaincase. 18/40=2.22:1 gear ratio, 19/42=2.21:1 gear ratio, and 20/44=2.20:1 gear ratio, personally I like the stock set up(19/42) over the 18/40 that you chose.
Just my .02

Your 05 900 has the larger 11.35 chaincase so:
19/41 (2.16:1 gear ratio) will take a 90 or 92 pitch chain
18/40 (2.22:1 gaer ratio) will take a 90 pitch chain
19/42 (2.21:1 gear ratio) will take a 92 pitch chain

thanks for the inputs buddy.
i do like the 18/40..but i think i have a 19/41 also laying around..so i think i willl give it a shot and see..as long as i can use the same chain..(cant afford to buy a longer one)
will it throw off the speedo..didnt know last tim ei went cause my buddies speedo never works..haha..
