Jeez man, any hot water left in the county?
Or are you helping us build a LNG pipeline to keep up with your supply and demand?

I'm starting to think that Christopher has stolen my sled
Or, maybe he's still playing with his rubber ducky
Will be good to hear the reports from Alpine.

Hence the term

glad you tried both.... Amazing difference isn't it?!!??
Those guys make great stuff!!!!!
They told me they had adjusted the air pressure over night.
The difference between the Black sled and the Green Sled was HUGE.
Both my son and I got to spend some time on both of them and felt exactly the same.
If my only choice in life was to ride the green sled or give up snowmobiling, I would never ride again. Whatever they did to it over night, DESTROYED its ride-ability on trail.
Its SOOO true.
I just collapsed into bed and gave up!

interesting, it rode like it was on rails when i was on it....which is interesting...I could not imagine a sled riding better on the trails than the green one...However in pow, it was a little harder, but not a lot...which is really a lesson to all of us with air shocks, it can be 5 PSI between horrid and awesome...

BWAAHAAAA....LMFAO.
What little energy I had left in my tired old worn out body the hot water stole from me.
Sorry for the LONG delay in this post.
here is the story....
A "certain company" contacted me a few weeks ago about a whole new prototype suspension they had been working on for the Yamaha Nytro, 2008-2012 editions.
Over the course of this winter they had built up a couple test mules and wanted to know if I would be interested in taking them out for a ride and offering some feedback as a fairly typical "Intermediate" rider, not as a hard core hill climber or well seasoned veteran with many years of back country experience. The plan was to meet up at the West Yellowstone Expo and spend a couple hours test riding.
Well, weather being what it was, they got nailed and delayed and we were not able to hook up. Fast forward to Friday last. The company and several of their employees traveled from West Yellowstone to Alpine Wyoming to participate in a 3 day "Next Level Riding Clinic" with Dan Adams. I had tried to call them on Thursday but the company cell phone was out of service, so knowing they were in the class, we just drove up to Alpine hoping for the best and arrived just in time to join in on the morning warmup before they left for the day's ride. What I thought was going to be a 1-2 hour ride, turned into a full day with group while they were in class with Dan.
(Just a side note here. I was VERY impressed with the operation that Dan Adams had put together up there. Its not very often that you get a free peek into someone else's classroom when your not a student. But Dan was gracious and allowed my son and I to tag along for the whole day's course and ride, and I liked everything I saw. If your seriously interested in improving your technical riding skills, I would heartily endorse his class. This is not a RIDE WITH ME clinic, this is an actual course of instruction designed to make you a better, more competent rider. I plan on returning for the full class)
So, what did we have to play with.
2 normally aspirated late model Yamaha Nytros.
Both running this new prototype suspension, but with subtle differences.
The "Black" sled is SCMURS ride and the "Green" sled was the shop's own test mule.
While the two sleds were similar, they rode as different as day and night.
The primary difference between the two test sleds was the ride height and the A-Arm Width.
Black Sled = Higher Ride height and narrower Arms.
Green Sled = Lower Ride height and wider arms.
It should be noted that the green sled also had a new prototype "Freestyle" seat that took you down to only 2 inches off the tunnel! The center of gravity on this sled is as LOW as you can go!!
Most of the day I rode SCMURS Black sled and my son rode the green sled. Had I understood how HUGE the differences were, I would have traded with him sooner.
Sadly, the bone stock Nyto is not know as one of the best handling snowmobiles being offered right now. In fact, it has some really significant downsides.
They dive, they are unpredictable, they dart and seem to go wherever they want on the trail. From what I can tell, the 2008 were the worst. However, I LOVE the Nytro for many other reasons. With a little bit of work and effort this sled can be "transformed" into a very sweet ride. While it is not likely the Nytro will ever become an M or a Pro, riding this new prototype shows it can be extremely close.
So, what exactly have they done?
This front end moves the spindles forward 4.5" and increases the caster angle to about what the Pro and the M are running.
They also narrowed it a little and are running the EVOL shocks.
They feel the Nytro front end is positioned in the wrong place which affects the balance points and the manners on the trail.
They found (as did we) DRAMATIC improvements in the sled's abilities and predictability.
The Yamaha factory made improvements after 2008 model, but they didn't think Yamaha went nearly far enough. Their thought was that pushing the skis further out in front of the sled (ala Arctic Cat) deals with the nose diving and the big time unpredictable nature. The new front end drops about 6 pounds and they also built a tee top steering post that drops another pound.
Riding impressions.
Some of you may recall that I installed a set of GEN III skis on my sled this year, with the most noticeable effect being that it was "easier" to turn the skis when at a dead stop. Not a huge thing, but it was very apparent to me, and made it easier to change direction of the ski when stopped AND when moving very slowly...
The first thing I noticed about the test sled, which had the OEM skis on it, was how EASY it was to turn on the trail.
My personal #1 gripe about the Nytro is the horrible trail manners. Like it or not, I have to spend a good portion of my weekend on trails getting to my favorite playgrounds. And piloting the Nytro on trails is a PAIN IN THE BUTT. Even with the OFT Steering Relocator kit, it still takes a LOT of energy to ride this sled around tight turns at speed and keep it going where YOU want it to and not where it wants to.
This new front end suspension reduces the amount of physical effort required to control the sled by a HUGE amount. While I "thought" the difference was big, I didn't fully appreciate it till I took my sled out and rode it on Saturday. The difference is DRAMATIC! It is MUCH less fatiguing to ride and require a whole lot less upper body input to steer.
The 2nd thing I discovered was how much easier it was to roll over and get up on an edge. I could lean this sled over, step OFF the running boards, and walk the sled through a tight turn without having to exert myself! The chance in the suspension geometry has resulted in a sled that is MUCH more willing to roll over and do what you ask of it without having to FORCE it. My 162SE is a PAIN IN THE BUTT to get over. It will do it, but there is no grace or finesse to it, its not "elegant" in the least degree.
The new sled is just the opposite, it was ready and WILLING to roll over any time I asked it to! It should be noted that my side hilling abilities are VERY LIMITED at this point in my sledding experience. That said, I did things on this sled I have never been able to do on mine! With no small amount of encouragement I found myself doing things I wouldn't have even attempted with my sled. Its manners are Vastly improved over the stock sled.
As a general rule, if you improve the trail manners you sacrifice the off trail performance, and vice-a-versa.
So far as I was able to tell in 4-5 hours of riding, this is NOT the case. they seem to have nailed a winning combination that makes the sled behave better in both ON and OFF trail riding.
If they take this into production this summer, then it WILL be on my sled next Winter!
Some comments on the Green Sled.
This is what they were calling the "Freestyle Sled".
It had a very low center of gravity with a slightly wider ski stance.
If I understood it correctly they changed the center shock air pressure quite a bit Thursday night to see what differnce it would make.
With my limited experience, this was the single worst handling sled I have ever ridden in my life. I swear this sled wanted me OFF it's seat. It darted and turned and tried to buck me off every chance it got on the trail riding back. Apparently the difference in performance from Thursday to Friday that resulted from that mid shock pressure change was way beyond their expectation. The previous riders reported that this sled handled like a race car on the trail. that it rode like it was on rails. And for me it was just the opposite, it took everything I could to keep it pointed straight ahead and not diving off the side of the mountain into the river down below.
I simply wouldn't have believed that just changing the air pressure in one shock could so drastically alter the behavior of a sled!

OK, my thoughts are now posted.
For you.
Bud, you need to call the boys at SKINZ and order up one of their AIR FRAME SEATS.
I was amazed that you had the Air Frame running boards, but were still using that squishy soft seat!
You gotta STEP UP !
Tell me about that handlebar extender you were using, that looked really interesting.
And what have you done to your engine/clutch. Your sled ran REALLY nice! It was very pleasant to ride all day.
OH.
Be aware that your SPARE BELT is gone.
The green sled blew a belt and they "borrowed" yours to get it home!!
I am here to tell you, that with THEIR new suspension setup, the SHOCKS play a HUGE ROLE in over-all performance.
I can not overstate this.
I have spoken to several other people that rode the green sled in the days before my turn, and they all LOVED IT.
But both my son and I came away with EXACTLY the same feelings.
This sled scared the snot out of me coming back down off the mountain.
Off trail it was FINE, and had some really good manners, but the ride home was anything but pleasant.
