• I've received emails and PM's asking me about "Group Buys" and promotions.

    A Group Buy here on SnoWestOnline.com would be a situation where a normal member (non vendor or mfg) personally collects orders from other members. That member then uses those orders to negotiate a better price with the Vendor/Mfg for HIS/HER "Group" of buyers.

    Here is an example of a viable "Group Buy"

    http://www.snowestonline.com/forum/showthread.php?t=269222

    A promotion that has the words "Group Buy" in the title is still a promotion, and from the rules that were handed down to me by Harris Publications is that non-advertisers cannot run promotions or open sales programs on the forums outside of the swapmeet.

    If a members wants to become a group buy manager, maintain a thread and collect the funds and negotiate a group buy... as a member, you are welcome to do that as long as you are not attached to the business of the vendor or Mfg.

    If you are a vendor/MFG and you want to offer an EXCLUSIVE "SnoWestOnline ONLY" promotion that is exclusive to snowest readers, please contact me and you'll be able to put it up in the Polaris forums.

    Also, before any vendors/mfgs get all "riled up" over this know that the moderators are strictly volunteers and do not receive a dime from any advertising $$ spent on this site.

    As ALWAYS, since DAY ONE of me becoming a moderator, I have pioneered, supported and encouraged vendors and mfgs in getting the word out to our readers with "New Product Announcements.

    Have a great season.

    From this point on, all vendors/mfg's promoting Pre-Season tiered sales programs, in the Polaris Forums, that are not paid advertisers will be appropriately moved to the swapmeet section of the forums.

The rotating mass reduction has been a hot trend for a while. I have an Indy Dan long rod motor with his clutching and the heavy clutch cover actually added weight from stock by quite a bit. I took it off for a couple rides and put on a light weight cover. I couldn’t believe how much the motor vibrated and how rough it felt with the lightweight cover. I didn’t notice any difference in performance in fact I think the heavy cover performance is better the motor is so much smoother throughout the RPM range

I would personally not chase weight in the primary side of things for hte vibration issues mentioned above.

That being said, a twin trax helix for secondary is like 4oz lighter then the stock single. brake rotor etc that stuff all adds up. I wouldnt drop my life savings into it, but it definately adds up to a snappier sled thats for sure!

the heavy cover eliminates clutching inconsistencies and premature wear.

maybe thats because you threw the balance off by changing the clutch cover !

from the factory the clutch is balanced as a unit .. if you start changing parts out you will need to re-balance it

I see how that is possible but trust me it wasn’t a balance issue. The heavy coverI replaced it with wasn’t balanced either and I have a fully balanced clutch assembly on an 800 with a lightweight cover and it’s not any smoother also the maker of the lightweight cover said I shouldn’t need to re balance after installing the cover.

Torsional vibration increases when the crank mass is reduced, .....hard on clutches, and much harder to get belt grip.

Thought I would hear more positive information on this.....May just send my clutches to Patrick’s for balancing

Old school Sledders won’t recommend lightning up the primary clutch. I say, if you will sell within 2 years, then lighten it up. If you are keeping sled long term, don’t lighten it up.

Don't want to argue with your comment however it is not correct. The stock cover has balance holes drilled in it. If you remove it you have affected the balance. This is why our Happy Face cover has balancing holes pre-drilled in the face so weight can be added to balance the clutch. Look at the ZRP site. They recommend re-balancing when adding their cover also. The biggest advantage to an open design cover is the heat reduction factor by allowing air to pass through it and transfer the heat away from the clutch. http://www.cascadecp.net/Polaris-Clutch-Cover.html

Ok let me start from the beginning. I agree that clutches should be balanced. I started with a completely balanced clutch assembly from Indy specialty. The bolts backed out that hold the replaceable center bushing on. I called Indy Specialty and they wanted me to send my clutch in for warranty replacement Of the cover and re balance but I was leaving on a trip so I had them send me a new cover and we could balance later. The cover didn’t make it in time so I threw on the ZRP cover I already had. I didn’t notice any performance gain but did notice the motor was much rougher. When I got back I put the unbalanced Indy specialty cover on and it was much smoother. My 800 actually has your happy face cover that is fully balanced and it’s not as smooth as the 850 with the unbalanced heavy cover. I understand ideally everything needs to be balanced but I still don’t think that was the issue in my case. I also made a big climb while on the trip and my clutches got smoking hot I have never seen them that hot with the heavy cover.

Sent primary clutches out to Patrick's for balancing, one 800 and one 850. Going to leave it at that for now. May send my driven out later on, we will see.

Sent my primary to Indy for a balance and cover, I had wanted the heavy cover but Dan did not have any at the time, so had the windowed cover instead. Sled is so silky smooth and very mild clutch heat, nothing else Ive ever had even comes close. Belt life is a non issue!

I’ve had the Patrick’s on my 2020 axys 850 for 1,600 miles now. This is taking weight out of the primary by shaving material off the clutch and adding a carbon cover and ti cover bolts. The secondary is about a pound lighter as well. There is absolutely more bottom snap and improved throttle response.
I replaced the weight bushings at 1,200 miles. They were shot and hitting the tower. That’s about the same longevity I get on stock primaries for the axys before needing maintenance. I clean the clutches regularly and blow them out after every ride. I do notice some vibration. I’ve never tried the heavier indi dan style, but would really like to ride them side to side!
Is it worth the $800 I paid? Probably not, but chasing weight reduction and bottom snap has been a priority for me.
