Nobody needs power steering on a sidewinder if it is set up right. The first thing to do is take off the stock skis and throw them away. Then get a 15 year old BRP 6.9 ski or any rocker type ski. Set your front spring on the rear suspesion to its sweet spot and ride. The procross chassis is heads and shoulders above any Apex in any length. It is not even close. I have had both. You could not give me an Apex.
I would have to agree with you grub taking it as you are very well experienced at setting up a sled properly. And, I believe you have a SW. The guy we were with in Canada, was not a very well, mechanical minded when it comes to setting up a sled, let alone a ultra high performance SW. Ski's were the biggest problem, and he had no sense about how to adjust his ski shocks, and, or the front of the skid.
whitedust, I intended no pot shots at anyone, not Yamaha, or any others. And by all means, everyone should ride what they like, and prefer. Brand, and model, as that's the only way for total ride enjoyment. However, I will admit, I got sucked into the Yamaha is going to bring out a "new, totally all Yamaha", snowmobile 6 years ago, or so. I was wanting to give the 4 stroke a try, and figured this " something all new, all Yami" would be the ticket. My riding bud was a Yami guy for many, many years. Well, no dice on that all "new"deal! And so, I am now very skeptical of Yamaha staying in the snowmobile business, let alone ever building a "new, all Yamaha" sled ever again. As to me, Yamaha doesn't appear to have any want at all to do so. However, AC is do for a new platform/chassis? That will probably be the deciding factor for Yami, as themselves being in, or out, as a snowmobile brand. Jmo, no harm, or pot shots intended at anyone.
