I ordered a set with the new sled I’m also curious if anyone has thrown them in yet. I thought the lockout was the best feature on my old cat.

This whole thread is power to weight ratio. My sidewinder ripped but it’s advantage became nullified in the ultra deep snow what I’m saying is they float like a lead ballon in the deep. I even provided solutions to this problem longer track or more track speed. After spending 13 years on 4...

I agree with some of this they could modify it to make it better. Thing with power engineering is you have to be the jack of all trades master of none instrument techs, electricians, millwrights are not around 24/7 like us so to be good at it you have to have overall knowledge of everything...

You ended with this and it’s where I picked up.

Few things hill start you cannot roll back you have to stop put it in neutral left foot down hands up right foot on rear break. Then reverse it put it in gear and not roll back. You can ride the clutch all you want but if you stall it not good. All the stupid road rules that you never follow...

What’s crazy is how small the number actually is. 125,000 units sold world wide every combined brand of sleds. Compare that to Honda or Yamahas individual motorcycle yearly sales in the millions. Sled sales peaked in the mid 90’s legit stats.

The problem with your Torque theory is those big sidewinders do not float in the ultra deep the 3.5 to 4+ feet days. So you have to overcome 108lbs extra weight and the drag of it acting like a mastercraft with full ballast compared to a ski boat up on plain. I found my Apex and Nytro made so...

Which Daltons did you grab?

How much snow on pole at Cabin?

I don’t disagree with profile being important but I just skimmed that 319 post thread on your “super sidewinder” I seen everything from breakdown of cost gearing changes the mph you achieved on stocker all good stuff but for his sake I didn’t see exact clutch set up. What flyweights/spring...

Your making me question a few things with this statement. I agree atmospheric pressure is 100ish kpa at sea level and at 8000 feet drops to 10.3psi(70kpa). 4 psi closely matches that pressure drop of 30kpa at elevation. So to maintain your 100 kpa 14.7psi absolute you need to add 4psi(30kpa)...

I also found my MTX clutching was always quite warm especially in the deep heavy snow in Revy area. As you already said get as close to alignment spec as possible that helped cool down belt somewhat. I tried more wrap on secondary as it’s something that used to help on Nytros but never found a...

I know the bone stock Mtx weights were 55.5g as you say if you load them up likely closer to your number. I ran the evo stage 4 at 6-1 70 deg with dalton springs. Flyweights were Qay 62 Dalton’s with extra 4 grams 66ish. I would think you should be pretty safe going with the Qay 58’s as there...

I would for sure try that it takes 10 seconds to unplug easy access.

What an absolute beauty he was

I actually don’t doubt that as my 18 cat was exact same. But after a dozen years on the 4 strokes I’m defiantly having fun on the 2 smokers.

This is a very tuff call the turbos are basically made for elevation the advantage is huge. I will play both sides I believe there is a balance point and that’s why these 850 turbos are so popular combined with being the first OEM. When you think of the 20% loss in power minimum at 8000 feet...

I think I paid $19 for my sidewinder in nov 2016. So use that price and add the big mcxpress kit another $5500 add $500 for clutch components. Battery was $350. Probably easily 25k. The new 850 turbos likely 22k out the door.

I had the same cr resonator, 4lb lithium battery, intake, did the 250 flash daltons, think I was running 6-1 70 deg wrap with stiffer dalton spring at the end it all worked decent even had qsl lockout. My point is they do not make enough track speed to float like the 800’s in the ultra deep...

I put 2700km on my sidewinder I think that your weight number is low but none the less the problem I found is that weight is completely in one spot up front. On the really really deep days I found that the 800 cats and 850 doos get up on the snow and float where the sidewinder is kinda like a...
