4 Stroke or nothing

Had to do it on flat land sleds as well back in the day. Stock engines not so much but it depended on the jetting.

That would be for modified engines, correct?

If anyone wants to see a MCX Stage 3 - 174 rippin around this guy has some good videos!

153 looks like some fun.

Yes and No, Factory jetted sled were fat, guys who played with the jetting on stock engines, knew the risks of temp and elevation change.

My 440 XCR was a horrible thing to keep jetted correctly, the engine was stock but sometimes I have to jet in the afternoon if the temps warmed up and vice versa.

Why is it that most of these sidewinders seem to be tail walking most all of the time? Is it just for the fun factor or is that the rear suspension needs to be coupled better?

The stock skid isn’t coupled. The QSL shock helps, but it isn’t the answer on a boosted 4S with a 3” track. I’m running a Kmod skid on mine, and under power it still carries the skis 2.5’ off the ground in position 1 when climbing. That said, I think a lot of riders love making them stand on end, simply cause it does it easily, and it’s fun to do it at will with a squeeze of the flipper.

the carbides on my t-nytro still look new, with that kind of power it is tough to keep the ski's on the snow

Cause we can all day long with ease.

Depends on what you want your sled to handle like. One friend has a baker skid with 174 and it’s VERY planted. Too much I think but it climbs like nothing else. Other friend has a 162 with stock skid and his skis are in the air a lot. The 162 is way more fun but the 174 climbs steep better. Pick your poison.

I guess that would make the front end seem light for sure if the skis never touch the snow.
The 162 definitely looks like a lot of fun. Could be interesting in steep climbs though?
Is that catman 10 with the baker skid and the 174 ? I hope that he gets his clutching dialed in this weekend. I know he is hoping for more track speed.

I lied the skis do touch, on the way down...

My 174 with the stock skid is very composed and surprise last season to hear people claiming to have wheelie issues and installing lock outs. In fact i don't find any reason to make any changes. It works extremely well. I originally thought i would of had to upgrade to a lock out but not needed.
I can easily control ski lift too sky is the limit to very little all with the throttle. I love having that type of control, especially turning out of a tight spot.

A little sidewinder action from the weekend. Sidewinder is still king when it comes to climbing.

 

[06 Dragon]

Thanks for the video. Did Catman 10 get it dialed in like he wanted it this weekend?

 

[Catman10]

Yup its pretty close now, just some playing with the helix angles in my future.

Just wanted to give some findings to the winder guys I went through a belt earlier than normal was getting about 1000km per belt then started to take one out at 350km. First thing primary spring was broken could have caused binding for sure clutch faces were way hotter than they should have been went to black bronze from dalton flyweights are at 65grams and all of my rollers are good. Next I backed off my secondary twist also dalton black orange from 9-1 100 deg to 6-1 70 deg I thought I was slipping in secondary at one time but it was actually a ripped charge tube this extra twist was likely robbing me of some down shift and track speed. Last thing I did was remove shim behind secondary to get alignment closer to spec also let’s secondary float a very small amount. I can say I worked this sled really hard last weekend and clutch face and belt temps were significantly lower and man did the sled rip. Defiantly lines up with others thoughts that you need to properly load this crank up. I also threw the fox qsl on the rear of the sled by far the best upgrade I’ve done other than flash 200psi chamber lockout makes it insane like the old school m10 two clicks later it’s soft and ready for the trees.

With the lockout shock it stays planted pretty good now... did a lot of chutes no probs.
