Clutching a stock Pro

[Danbot]

Not having any luck with searching. There is lots of contradictory information on the subject, plus it gets mixed in with mod clutching which is irrelevant for me and I'm sure... many others.

I'm looking for a little help with consistency on my stock 13 Pro, she is overly sensitive to elevation and conditions, or at least in my opinion.

-Stock 13 163 other than SLP can
-10-62's and SLP blue/pink, 1 Thunder products slip washer on the clutch face side, 1115 belts.
-Stock helix, stock spring, 1 Delrin washer under the spring cup.
-Usually unload at about 3000', ride the majority of the time between 5000 and 7000'.

My rpm is typically a bit high leaving the truck which I can work around... (8300 to 8450rpm). I'm almost perfect at 5-6000' (8100 to 8250rpm), but if I venture up above 7000' it can get as low as 7900rpm depending on conditions. Traction/load changes while climbing also seem to pull the rpm down fairly hard for a brief moment.

I will say that 1/4 to 1/2 throttle situations in the trees is awesome, I like the response, and backshift. The setup works very well here.

I have a black/purple secondary spring to try, but I have hesitated... not wanting to have a bad setup on a trip. Riding time is precious. Any experience on this spring in my elevation range on a stocker?

Heel heavy weights seem to be popular, but getting my belt to sheave clearance adjusted, and a re-balance is going to cut into my ride time. Do any of them fit well without clearance adjustment?

Any thoughts or advice would be awesome, and greatly appreciated. This place can sometimes be an ocean of tidbits to dig through. I think I was spoiled with my 900RMK where a few guys figured out what worked and layed it all out for the newbs in places like this.

Search for MDS clutch weights.. quite a few threads on them. I have them and they have been fantastic. Steve at MDS is awesome to work with... give him a call and he will help you out.

that's just too big of an elevation change to get it good with one setup..SLP mtx weights should fit without reshimming the spider(designed to tighten stock clearance to specs), I didn't like the black purple in the sec..think the stocker works better on the pro...I would drop finish angle on the helix for over 6000 ft(will help the back shift in deep snow a lot), and would look to a helix in the 60/40/.40 range personally..that 42 finish angle is pretty tough to pull at higher elevations. also if you go to a team green?( it stacks in between the slp blue/pink and gree/pink springs for tensions, it seems to work better on the pro then the slp springs. You will have to set for a bigger over rev down low and just keep it off the rev limiter in order to make it work better up high, or you will be having to re clutch every time....long thread in the dragon section about clutching these motors, and while the pro seems to like a slightly different twist, that thread should give you lots of good info....

With clutching the Pro, the clutch weight change out elevations seem to be 6700', 8100', and 9800'.

In an effort to save you a lot of time and headache I would go with Polaris recommended stock clutching, I've found that it is very hard to improve on. I've tried most every tuners recommended clutch set-up over the last couple years and continually go back to stock for the best performance. The stock 140/330 primary with 10-62's up to 7,500', above 7,500' run 10-60's. The black purple is a must above 7,500'. The stock helix 56/42 works well with the black purple but is a little lazy with the black. The 1115 seems to be everyones belt of choice, the 080 will yield similar RPM's and the 1122 will run a couple hundred R's higher (not good)! Tune your primary for 8,100 R's in a big pull and I think you'll be happy. I have several riding buddies who have tried several other set-ups over the last couple years and they all prefer the stock setup, it feels a little lazy but when you run it side by side for several hundred runs over the course of a few years we've found the stock clutching tuned between 8,000' and 8,100' continually outpulls everything we've tried.

He has it pretty well dialed in. Love his kit on my 14.

Think he is IQRider on here.

I had his clutching in my '11 after about 2 months of wondering if the pro could get any better or not. (I was wrong BTW). His clutching woke it up so much that when I got my '13 I installed his clutch kit before it saw snow as i assumed it as essential equipment.

Thanks for the replies, and merry xmas to everyone!

I definitely have an opinion against clutch kits, especially when the specifics are a mystery.... leaves me with no starting point to adjust from.

I have been and will continue to read the clutching threads in the IQ sub, thanks for pointing that out.

He gives you all numbers, rates and original packaging. The parts of the kit are factory pieces. He just figured out the right combination of springs, helix and weights.

How do I get the dam weights off.... nut is so close to the primary. Cant get any socket or wrench on it....
We're about to grind a socket down to make a super thin walled socket....

3/8" wrench, use the open side on the nut..... it will not fully seat, but enough for you to crack it loose with the allen key from the other side.

Clutch for 8300 at 7000 ft in 91 mode.

when running at 5000 ft put in eth mode and you lose 200 rpm. Soon as you start seeing 8100 flip to 91 mode.

Call me crazy but at home i clutched for 8300 in eth mode. I figured out hot to change to 91 mode and was revving 8500.

A 3/8" ignition wrench works very well.

Good decision. However, if you are loking for more consistentcy over a bigger range of altitudes and snow conditions, the Team Tied is a very good option. Their setups work great on stock Pros and you can take the clutch with you when you sell the sled.

What setup are you running in the tied Bossman?
I put one on my '12 Assault last year, but it didn't really seem to "like" my sled.. Just curious what folks are running with the tied setup?
I run from 3,000-6,500'

Thanks

team tied 71 55 .46

red black spring ( one delrin)

5500-8000 feet

motors totally stock (so far) lol

so far so good and i'm still messing with it

Ran the 73/57.36 in the 155 sleds from 6000-10,000 ft and 71/57.36 on the 163 models, both with Red/Blk 140/240 springs. Set them up in the 55 finish angle for heavier riders. Would have probably ran a 73/57.46 with 140/240spring in yours with 66 gram weights cut to 65 grams for your elevation.

Agreed , I'm 6'6" and about 295 in my gear, it needs the 55 and I may have team do a 53 for me

Cool thanks for the reply!!
Still have yet to take it out of storage, try and get this combo together in the New Year!!
