      I've read that you've machined your primary for Overdrive. My Nytro just rolled over 15000km, and I plan to do some clutch work and install 2 speed turk setup. When you machine for overdrive do you only machine the bottom faces of the clutch sheaves, or have you changed the angle at all? Cheers

        Just straight cuts on the bottom faces of the sheaves...then radius the corner with a file and emery cloth to blend in the angle

      Hey Nos-Pro. I'm looking at a thunder products clutch kit for my stock sidewinder ltx-le..with studs.... how do you think this kit will affect top end speed? Which belt should I use? Thanks!

        Thunder Products kit is designed to improve the entire range...bottom to top, but still giving a very low 2400 engagement rpm so you can pull up to a gas pump, cross a road or load a trailer with ease....not high engagement so you spin the track all the time. Plus the low engagement will work awesome for those in the deep snow as the sled will crawl on top of the snow instead of digging holes.

        Gearing is limited in the Sidewinder and you will want to check what gearing you may have. I think the LE came with gearing that will come out of the hole like a scared rabbit, but you will run out of gear at 100mph. A clutch kit won't help with top speed if you run out of gearing. Just being honest.

      Hey Nos-Pro! I have a nytro mtx and I put a slip on pipe and fuel controller on last year and when I hit the gas I'm now hitting the rev limiter. I know I need to add some weight and was thinking about getting the heavy hitters. What weight should I start at and how much adjustablity is there? Thanks!

        Go with the 48 gram weights and you will be set :)
        They will go up to middle 50's for total weight....more than enough.

      Hi Nos-Pro. I have a 2012 Vector with a very noisy primary, at just over 18,000 KM. I added the Schmidt Bros quiet kit but there was no improvement. I read about the stub shaft from the crank so I pulled the primary yesterday and while I did not remove the stub shaft, I could feel virtually zero movement. I am thinking I maybe need a rebuild, but would really like your opinion as to most likely culprit.

      TIA,

        No, if there is....I don't know as I purchase everything separately from Yamaha (weight bushings, clutch cover bushing, moveable sheave bushing, plastic shoes for the spider, rollers and washers). The clutch also has to be taken apart where you need a grunt tool. These tools are not cheap, so people have their Yamaha dealer take it apart.

        Hope this helps

        How do the sheaves look? If really used, there will be cracks at the bottom by the main shaft. For what you can buy sheaves and parts for, you could get a clutch from Barn of Parts for $250

      Hey Nos- pro I am thinking of getting a Big venom clutch kit, I can tinker a bit but I have never done a clutch kit. Is this kit pretty simple to install and fine tune? Thanks for any info you may have.

        Hi olite72 :)
        Yes, the kit is very simple to install and there is a video of the installation in the thread "Big Venom Kit". Lonn from Thunder Products has also included a manual that is very helpful in fine tuning the weights to your liking. When ordering a kit, tell Lonn your information and the weights will come pre-assembled and be very very close if not spot on to your riding, weight and altitude :)

      Hi Terry ! My name is Alain and I from Quebec. I saw a fews post from you about your Clutching since last winter. Thank you are very generous to help us.My LTX is stock .I just bought mbrp can .
      Now I have to make choice for the best set up . I'm not sure if the 8fp weight are the best for the acceleration corner to corner , drag , etc? Did you had a chance to compare your set up with the others like DD, ulmer, etc.

        Hi Alain, the 8FP weights put a lot of squeeze on the belt (which I am running the 8DN belt now) and really can be used for off-trail, accceleration and drag. It's how much of a rivot you use at what elevation. I am down low at about 600-1000 feet elevation. If you are higher elevation, you need less weight.
