Thanks! I think it's a mountain thing. Rides exactly like my 16 Viper MTX did at low speeds...terribly. Haha

2017 Sidewinder 162. Terribly jerky at slow speeds. High engagement. Has anybody figured out the best Yamaha primary spring to put in for low and smooth engagement? I put a pink pink pink into my Viper MTX 141 and it made a huge difference...love that sled now. Thanks for any experience!

Great tip, talked to him on the phone and he is great. Great prices.

Looks like it is down to the 2.25 Powerclaw or the 2.5 Camso Challenger Extreme. Has anybody used both of these? Is one known to be more durable than the other? Thanks!

Tracks USA has a 1.75 backcountry or a 2.5 challenger extreme. I do like the 2.25 Powerclaw, and don't really want more or less paddle than that...but I find the smaller paddles on the edge of the track rip off fairly easily where I ride. Are there track options with just wider paddles, and not...

Hey guys, am hoping for some help! What track options are available for Viper MTX 141 se? It is a 2016. The 2.25 powerclaw it came with is almost finished. I think I would like another 2.25" or maybe a 2". What is available for this sled? Thanks in advance!

Nope, worked great. Can tell you the RPM once we get some snow here!

I am very happy with the Cannondale spring. Was a game changer for the sled.

What would you guys suggest for replacement skis on a Mountain Max 700 144" 1.5? I ride almost exclusively off trail in Canadian Shield powder. The wider and more float the better is what I am thinking. Years ago I replaced the stock metal skis with Camoplast All-Terrains and the difference was...

I am not an expert, but I can only imagine this would be caused by not enough ski pressure?

I would have said 141! You described the exact riding I do in the Shield. It is great, although I don't really love the sled on trails. My 97 Mountain Max 144 1.5 is better for trail riding

I love my new 160lb spring. Huge difference, steering was way too heavy before. It's like a new sled. Other key mod was adding the pink pink pink spring to the clutch. High rev engagement was fucking ridiculous before. With these 2 mods I went from not really liking the sled to loving it. Total...

Thanks a lot buddy! Went with OEM from Rocky Mountain ATV! Gotta take good care of the Mountain Max.

I meant to reply to this thread earlier! Installed the pink pink pink spring last spring. I LOVE IT! A total game changer. Totally smooth engagement now, and crawls through the bush portages sooooooo nicely! Just excellent. Paired with the 2019 flash it is beautifully smooth at very slow speeds...

Appreciate this first response! Will also be curious about whether a used Yamaha part would be better than a new aftermarket.

Has anybody here had experience with aftermarket stators? My 1997 Mountain Max 700 144 needs a new stator. Yamaha $500, aftermarket $150. It is an old sled, but I do love it! What would you guys do? Would love to know if you think the sled will be as good with an aftermarket stator. Thanks in...

We are snow starved in Manitoba right now! Is anybody in NW Ontario up for a ride? Would love to check out the Atikokan area sometime. I would rather ride off trail though...my paddles are a little big for hard packed trails haha.

Has anybody found a good skid plate for the Viper yet? Bought the Yamaha rear skid plate and went to install, but it is ridiculous. To take that thing off and back on for every oil change is absurd. I would rather just replace my fucked up aluminum every year. What is best option here? I do a...

My 2016 MTX with new flash no longer needs 2 starts when warm. Started right up at -20C, but haven't done any super cold starts with it yet. Happy so far.
