clutching

Wondering if anyone can help with what to run for Springs, Weights and Helix Degree when riding at sea level and also the set up for the mountains. I bought the DYTA-2 (79-86.4) Dalton quick adjust weights. Currently have it fully loaded at elevation. Any help would be appreciated.

Hello, So we own a 2012 venture GT, We purchased the sled with 300 miles on it and I noticed the spare belt was gone when purchased. The guy we bought it from played dumb. Long story short 1100 miles now and burned 3 belts. when driven under a normal load this thing will over heat belts...

Hi, Just bought a used 2009 Nytro MTX 153 for a backcountry hut access machine. I want to take the kids on it, tow a skimmer and be able to get up into the mountains on logging roads. Cost, durability and reliabilty are all musts, which is why I went with a yammy. Can you give me advice on...

I'm running TD powertrail, ulmer primary spring, stm weights, stock secondary spring with a 35/39 dalton. I'm not sold on the reverse angle and feel there may be something better out there. In my SRX days we always ran 3 or 4 degrees higher than stock start to 3 or 4 degrees lower on finish. I...

Is anyone running this combination? I'm not sure how much weight to add and I can't test because of the melt, I'm heading north next week and would like to at least be close on the clutching. Thanks

I have a stock '08 Nytro MTX (as far as I know and the springs are still stock colours) and when I am running full out, my RPMs are up around 9200 and will stay there through 120kph. I did not go much more because I was not sure what safe max RPM is on these engines. How can I get the RPMs to...

I got a great deal on a new MPI 190 kit on eBay for my 2014 viper xtx and I'm making sure I order everything I need for the install. I've read just about every turbo thread I can find on here but I just want to get a little advice. I'm new to turbos but I've worked on my sleds for years and...

We have developed an all in one speed upgrade for your MPI 190 turbo SR Vipers. This kit includes a new lower gear, hyvo chain, machined helix with overdrive acceptance, secondary spring (set at 3-3), and secondary washers. We have seen drastic improvements over stock gearing/clutching as this...

So what's the best clutch kit to go with on my Yamaha viper, it's a 2014 Yamaha viper Xtx stretched to a 162 by 2.5 track, has the 190hp mcx turbo on it, currently has all stock Xtx clutching in it and pretty much hits the rev limiter at half throttle. Most riding will be done in the prairies in...
