We've now spent several days working on the '08 Summit 800 clutching.  We tried several ramp and spring combinations before settling on one that we really like.  As usual, the stock clutching picks an RPM based on speed and doesn't stay consistent like it should.  The new setup gets the clutching back in a smaller window and holds the engine where it makes peak power.  In our back to back testing, the new clutching also significantly reduces the operating temp of the clutches.  In addition, this combination also coasts better and reduces the lurchiness of the stock clutching. 

We've also had some good really deep snow to test in on the way to Buffalo from Rabbit Ears.  Kenny Huismann, our resident professional hillclimber, has also been riding our test sleds and his new X, which means there's been plenty of "hold it to bar" kind of rides.  In spite of really abusing the sleds and running a belt that the stock clutching had pulled some of the cord out of, we haven't had any more belt problems. 

As always, the new clutching will be installed on any sled that we sold at no charge.  The clutch kit will also be available for $399 installed for anyone who would like the added performance.  As always, I'm still a big fan on the side panel vent kits.  Anything we can do to get some hot air out of the sled is a good thing.  We've been extremely busy in service so please give the guys a call to coordinate a time to get the updates done. 

In addition, we have also finalized our Xtreme setup on the Yamaha Nytro MTXs.  Like the Apexes before, the Nytros have a very nice flat powerband but it's still important to have the clutching right and be turning the right RPM.  We found the stock clutching was close in hard pack conditions at relatively low altitudes, but it still underrevs in deeper snow or at higher altitudes.  To that end, we have a new combination with some modified weights that will keep the RPM correct.  In our comparison testing with other sleds, the updated clutching makes the Nytros even more competitive.  As with the Ski-Doos, the clutching is free for those folks that purchased from us and also available for $399 for anyone who wants to upgrade. 

Thanks,
