Vector clutchs

[trapper]

. I have a '12 Vector and really like the sled. I have been on Polaris for over 30 years. The last 2 Polaris had M-10 suspension and they worked very well, I like a smooth ride, I'm not a ditch banger or lake racer just a older rider who loves the sport. I Switched to the Vector as I rode a friends and the ride was very good, and with the EPS it's a great sled..

My quarry is this. The Polaris' have very good clutches. Smooth operation, cool running, just great. The Vector has a very harsh engagement and the secondary has about 3 inches of slop in it. You can rotate the secondary back and forth when stopped. This makes for very clunky engagement and not smooth at all. I reverse into my garage and this is hard to do when the clutch grabs so violently.

Is there anything I can do to make this work better, and is the slop in the secondary normal?? When I first got the sled I wondered if a Polaris clutch would fit on this motor. If the taper was the same (I doubt it is) I would get a Poo clutch for it. This would not rectify the slop in the secondary though..

Any help and information on this would be most helpful and appreciated

Yammie clutches are very durable and work well when tuned properly. I set of 14.5mm rollers in the primary will help take a lot of harshness out of your engagement. A primary spring with less preload, and similar total force spec. would be an option as well. Just remember that the spring rate will affect the entire shift to some degree. The "slop" you are feeling in the secondary is actually part of the reverse gear set up in the chain case and is completely normal. If you take it apart one day you will understand how and why it is there. Cheers

Thanks for the reply, Stubby; The roller change sounds like it would be a fix as I'm guessing that the 14.5 roller s are slightly bigger then the stock ones. Where would I get a set of these?? As for the secondary spring, yes it would change the whole profile of the clutches operation by shifting gears sooner, maybe not a desirable thing although it might give even better MPG..

I believe the roller change would be a good place to start. Thanks again for the info..

A Comfort Clutch Kit from Schmidt Bros. in Michigan will get you exactly what you want. 3 custom rollers and a primary spring for about $140. Schmidt also sells a kit for $10 that quiets down the at idle rattle. I have all of this and wish I would have done it long ago!

And yes you can get Polaris clutches to work on your Vector. Google Hartman Racing (it's not a race setup) and look thru their catalog for Polaris clutches for Yamaha.

Hello Trapper! Did you buy the sled used? Previous owner could have made some clutching changes causing the harshness.

3" of forward and backward movement on the driven pulley sounds excessive. Check your chain adjustment, it could be loose. (Turn adjuster bolt in until it stops finger tight, then back out 1/4 turn.

Also, 14.5mm rollers are the smallest roller that Yamaha offers:

Does Schmidt Bros. have a web site I can visit?? The kit they supply for the money would be better(cheaper) option then a Polaris clutch..
Thanks

I bought the sled new so am guessing the whole unit is stock. I live in Canada but bought the sled at Bee Line in Minnesota.. I am familler with chain adjustment but new to reverse in the chaincase, my previous sled were two stroke and the engine reversed. The chain is as it should be. Would larger rollers help with the harsh engagement??

I recently put a set of 14.5mm rollers and a primary spring out of my xtx nytro, it made a huge difference to the engagement and smoothness. I had a set of 14.5mm rollers in my xtx last year so I figured I'd try them in my vector, same result...happy happy happy

I would call Chris at Schmidt Bros. directly. He told me about his $10 rattle kit while on the phone. I didn't see it on their website either.

Looking forward to hearing/seeing what it is, and if it works, then that's $10.00 bucks well spent imo.
