I second Knapp! Something keep the clutchs from shifting.

These machines will be way easier to steer with the Snow Trackers. I ran them on both my 141 and it help a lot. It is a must for long day pleasure of trail riding without tearing you up. The bad is I hate them when there is 4" of fresh snow on the trails as they tend to push. As far as weight...

I really like mine. So far only 500km with it. And like you said, it hook really well in any stuff. Great track!

Be careful of where the curvature is. More curvature are the beginning of the profile give ofter more rpm because of the angle at the roller. Take a look at the weight installed in the clutch on the workbench and see how it travel the whole cycle. And then compare with a flatter profile...

Remember that contact angle at the roller change the effort to push the clutch open. So even lighter, some flyweights with more curvature could give more upshift force. You can modify a flyweight with more curvature at top end and got really good results from a weight that was "too light or too...

For the 32 km I did with it Thursday on my 2025 SRX, I am really impressed the way it hook on a plowed icy road.

My 2018 Black Cat 144 modified with Yam clutches and other goodies is my favorite sled to date and a very versatile one. But, it is more of a straight trail racer and we do have a lot of fast long stretch trails where I live. But that machine is not as comfortable as the IQS set-up of the SRX...

I was also wondering the same thing but if you look at the video they did, look like 75% of lugs are in the direction for helping traction wich is perfect imo.

I was going to order a Cobra 1.352 for the 2025 SRX, but when I saw this one, cool. That one with more rigid lugs should have more traction. The only drawback I think of is maybe a little less top speed and less sliding in corners... I think I will give it a try.

Thanks! Never thought Yamaha had a 37 degree helix. Was that 37 degree offred to the public? Or they were all cut to 35-39?

I wonder why they changed the number from the 8KC70. Just saw that in part book they are all 8MA-00 or 8MA-10.

Really good info. Just to add, the Cat belt I blew was with stock tune 141 x 1.75 back country track and very low 22/48 gearing. Now I run MS17 header tune, 21/41 with a 144 Challenger cut down to 1.5".

I ran the Team for 3000km before switching. Original 220$ Cat belts were exploding at 1500km each. Both belt blowed at part throttle with excessive heat. Beeing used to run 120$ Yamaha belts that last forever, that dosent make sens for me. After put the Yamaha clutch I must say that I exploded...

No sorry, I mean the clutch was too tight in the sliders. Having hard time just to close the clutch without any spring on it.

Turboflash how is the belt lasting with the Team on your friends sleds? Mine was just too tight, overheating expensive belts and giving poor clutch response. Thats why I swaped to Yamaha clutch on my 9000 and do not regret one bit.

I ran the Tapp on mine last year. It was a really short season but after 1000km of riding and tunig, I still prefer the Yamaha primary. In my opinion, you can adjust more with a Yamaha primary. Like Knapp said, the clickers are nice, but they are not something that you play with a lot. You are...

I just checked the part book and it also show that new helix number...

I was at a 2023 snowmobile show today and opened the clutch side cover on the new SRX. I was surprise to see the helix was stamped 8MA10 on it. Can anyone with a 2023 SRX check if you have a 8MA10 helix on it and mesure it? Thanks!

My freind have a 2019 xtx se and he have de new controls like the 2020. He is all original.

The throttle is also different (a bit smaller) on the 2019+. I found on my 2018 that I used to drive with the hands not completely closed around the handle bars to be comfortable with the throttle. And that make my hand getting cold more easily.
