clutching basic-is for the IQ RMK and the dragons

[clutch man]

First of all up until 09 Polaris put in the same helix for 6 7 and 8s
lets go in to the motors for a bit
The 600 the shortest all stroke of them 64 mm fast revving motor but less torque. but Polaris put the same helix as the 700.
The 700 in the middle with a 68 mm stroke, more torque than the 600 but less than the 800.
The 800 with the longer stroke 70mm has more torque tha eather of the 6 or.

Just the laws of physic's tells me the you cant all run the same helix in all them.
The more torque the steeper ramp helix you will need to harness the torque of the motor. The less torque the smaller the ramp angle should be.YOU CAN NOT MAKE IT ALL UP IN THE DRIVE CLUTCH. You have to change the driven to match.
Other than the helix that they put in the 09 dragon, Polaris stock out of the box has not had it even close on clutching. NEVER HAVE ON THE MT SLEDS.
Polaris has been putting a 42 for the final on all the mt sled for years. IT CAN NOT WORK FOR ALL. The only one that will pull it is the new 800 none of the other will pull it good ( this is talking 6000 up elev.) the longer the track also changes how much final it will pull. Gearing can help pull more ramp on the final but not as much as you would think.
here is what i would recommend for each in the team driven
600 144/155 58-38-46 or a 56-38-46 stock spring
700 155/163 58-40-46 or 58-38-46 stock spring
800 155/163 64-40-46 stock spring 163 change to a blk/purple spring
Remember this is for stock with mod this will change.
Now the 900s Polaris was off the other way, stock likes a 64-44or 66-44 or64-42 or a 66-42
the drive clutch on most is not to bad. but would install the almond spring.
balance the weights.
This is just set up every thing else like belt side clearance, alignment, balance etc also apply's all this is delt with in other threads.

I would agree I have both an 08 600 155 and a D-8 163..personally the stock helix works good on the 7..to much for the 6 and not enough for the 8(I ride mostly from sea level up to 6 with a once in a while blurp up toward 8000 ft)..but down low I like the 62/42 helix best...and have found adding more weight and primary spring works better for me...down at these elevations...

Did you try a different helix for the 7 or did you just run the stock?
the 700 make good torque and the stock helix does not utilize it.
stock is OK but loading that motor more on the bottom is allot better.
even a 60-40-46 works good for the 7

he ended up running a 58/40 if I remember right...

that setup works very well

 

[sledsnowco]

What setup would you reccomend for a 2010 assault at 9000 plus elevation ?

 

[clutch man]

What setup would you reccomend for a 2010 assault at 9000 plus elevation ?

first of all i would change to a 19-41 gears.
drive clutch stock spring 60 gram weights
driven a 60-40-36 helix stock spring.

thanks clutch man,i was planning on regearing this summer.I'm not very familar with gearing,what will it change?Also i found that 10-56 weights worked the best above 10,000 ft.

If you run the helix and gearingi stated i think you can run the 60s if not maybe 58s
Also the helix comes with a 60-38-36 too and it may like that above 10,000

at low elevations I run 19/42 and many have said up high they have gotten best performance running 19/45..this thread has a few mentions on very high clutch /gear setups....

[clutch man]

The gearing and clutching will be different on an assault with a 146 track.
the RMK/dragons with 155 and 163 track need lower gearing for sure.
the Assault will not need as low of gears.

 

[IDPOLARIS]

Clutch man my 09 dragon is running stock clutching right now it has a 56/42/36 helix and all Black spring 160/240 so if i understand this right i should be running a 64/40/46 with a black/purple spring this will help the performance better. Now i ride anywhere from 4500-8500 feet i play in the deep snow and climb the hill's but also ride the trail with the family. I'am still trying to understand the whole cutching thing. Any input would be greatful

Thank you and yes

Can you post the stock helix numbers for the 6 7 and 8? I'm curious to see how these numbers differ.

 

[clutch man]

Polaris Did a one size fits all for the 6 7 and 8 RMK and dragon RMK
it is RAMP-DRVN(56/42/36)LWER part #5135403. This is the ramp that they used DOES NOT WORK FOR ALL and the 42 is to steep for 6000 plus riding and any of the models.

 

[MARV1]

I use an EPI clutch kit on one of my RMK 144's(600SB kit) and I'd say it works way better than stock overall from 0-2.5k'. Fuel economy is better, response is better, acceleration is way better and the other guys just wonder why I'm alot quicker than them and they have to work harder to keep up.

 

[whittaker727]

How much will the addition of a full SLP single set up and the addition of a Camo extreme change the set up needed for a 2010 155?

 

[starfire99]

Marv1.....Glen Erlandson told me himself....shallow progressive helix ie 54-42, is far superior to the 66,64-42's that polaris put in stock. On my prox800, there was 5+ sled length difference to 90 mph. Notice how most folks on here uses heavy springs and weights to work with the stock type helix's..........best way to prevent upshaft and get poor economy at part throttle.

 

[clutch man]

There our more then one way to clutch!! also do you wont load the motor hard for better tourque? or ski lift in a drag race.
most on here with dragons have 155 and163 tracks and need to load the motor so it will not trench (62, 64, 66, for you first angle does this.
