Viking/Wolverine Clutch Kit info

The clutch kits which are primary roller weights and secondary springs plus a shim for primary are for people who either do not want to spend the money for a machined sheave with these parts or have tires 28" and larger who really need some clutching but due to the heat caused by the big tires runs the risk of belt hitting the cover with the sheave.  More detailed info can be found by reading our Sheave Disclaimer article  Link to Article

The issue is, the big tires need the sheave the most due to manipulation of the belt for a lower gear if you will when starting off but due to the belt being so close to cover the ones with big tires as mentioned in article above create so much heat that it might cause the belt to hit the cover. We didn't want to just leave the big tire guys out so I decided to go this route.

So the info provided is about simply adding our High Velocity Greaseless weights and Secondary spring for better performance due to the larger tires.  Large tires drag engine rpm down and the clutch shifts out too fast with the bigger tires giving you a bog if you will or a loss in performance.

So what we are doing is going with a lighter roller weight and stiffer secondary spring that work together to increase that performance, might as well add some of our slippery washers with your new spring to increase the efficiency of the secondary clutch while you are at it.  For $13 they are a no brainer.  Click this link for more info. Link to Slippery Washers  Don't forget a Slug kit either, more info about that can be found on the slug kit page, link to slug kit.

Also I mentioned a shim, we will include two .5 mm shims to install before you put your primary sheave back on to space out the clutch a bit to lower the belt down similar to the way our sheave does but not as far.  Our sheave is about like adding 2mm of shim on the low end so the most we would use with a stock sheave is 1mm and you can play with .5mm or two of them. By adding them you are adding more low end crawling ability but at same time losing top speed. Each .5 mm shim equals a loss in top speed of 2-3mph.

Now to weight selection.  The use of 14 gr weights will most likely cause you to hit the rev limiter at times so we recommend the Power Commander we sell to raise the limiter up a tad.  There are other benefits of the power commanders and the Wolverine just needs one because they run extremely lean from Yamaha but you can read about them on this site, just go find them and read the tech articles on their pages.

I hate to put it only in tire size but you are certainly welcome to call me to discuss weight and spring choices in detail. Also, it is just really hard to put this in print, as different conditions and riding styles will change it.  So use what is below as a guidline and feel free to call to get more details if you need it before ordering.

Wolverine and Viking who have tires up to 28" Should use 16 gr and purple spring unless they are foot to the floor hill climbers then use 14gr and purple spring.

Tires above that can either use 14gr and purple our 16 and our new green spring

The green spring is going to be more for the Viking than the Wolverine. The Green spring is in between purple and gold on stiffness.

To decide which one, is not that easy but the 14 and purple we will call more aggressive and will have a lot more feedback meaning not quite as smooth operating.  Yamaha uses a heavy weight to make the driving experience very smooth but it sure does affect affect performance and once you go to taller heavier tires they simply no longer work well at all.

So if I was choosing between what I was doing and I was an aggressive rider hill climber foot to the floor type I would do the 14 and purple, for the normal riding I would choose 16 and purple for a Wolverine and 16 and green for a Viking.

Also, in the event you want to try a different set of weights Hunterworks will sell you a second set for $50 aftter trying these instead of $79 as on the site, no need in making money on you on a change you might want to make and a second spring is $30.  This is does not mean if you are buying two sets at once for two different vehicles then they are standard prices.

Lastly there is a screw that comes with the kit it's purpose is to spring the secondary on install so you can get the belt back on easy and make it easier to install the sheave back on.  Our machined sheave install video should be used as an install video for this kit.  

It is really hard to explain it in text and once again you are welcome to call me to discuss which way you should go.
