No issues with heat on my Viper MTX yet. I have drove in lots of sketchy conditions as well. I also have a turbo. The temp stays very consistent.
Everyone asked for a mountain sled to be 40 lbs lighter. The Viper mtx is 40 lbs lighter than a nytro mtx.

The Viper is NOT and i say it again NOT 40Lbs lighter then the Nytro, that is 100% BS from dealers and Reps trying to impress and make sales numbers.
If you compare the same spec'ed out sleds Nytro and Viper with 162x2.5" tracks the sleds are within 10Lbs of each other.
The Rep's and dealer's are BS'in you by using the spec's from a Viper XTX, which is a crossover with a short 144 low profil track.
BTW, is 40Lbs lighter then the Nytro mtx.
Love the way people will fall for BS because it sounds sweet to their ear's and its what they want to hear.
The builder, rep's and dealer's know that, thus why an actual weight # is not truely revealed yet but speculation and using # from a different model cover's their bottomside.
BTW, when i say 10Lbs, in reality closer to the same weight.

Lol. I will find the proof. An Alaska dealer weighed a Viper MTX and a nytro mtx and it was about 40 lbs lighter. It was documented with pictures in the Sr viper forum.
I have both sleds. The viper feels a lot lighter even. Easier to life front and rear.

I have a Viper in my shop we're building, we scaled it already, 545Lbs no turbo setup yet, that will most likely add another 20+Lbs. With the stock 162 track.
Our 2010 Nytro with turbo 570Lbs, with a 174X3.
YES the Viper feel alot lighter, that's called improved geometry over the Nytro.

Unless they are making a whole new version of these Viper from tinfoil, a 500Lbs 4stroke with a 162x2.5 track is BS.
Considering a bone stock Nytro with a 162 is 545Lbs.
BTW, we scaled a Cat M9000 with factory turbo and a 163x2.6 profil track, it was 570Lbs...stock.

IMO the Viper is a good improvement over the Nytro chassi wise in the fact the geometry of the sled makes it a better balance, lighter FEELING sled thus easier to ride.
Is it the answer for Yamaha....NO....the Viper is still way behind in design compared to the other 3 builder's.
Here are some of the problem's.
#1- Yamaha's commitment to the mountian segment is poor.
Now issues that should be addressed if your commited to being a real mountian sled player.
The running boards are still poor and do packup.
Check Polaris running boards for ideas, best in the industry for oem boards.
Radiator in a mountian sled???? is that a JOKE.
Radiator belong on trail sled's not mountian sleds.
Mountian sleds use "heat exchanger's" mounted under the tunnel, check out the other builder's for how its done.
The ski's, we're not sure if they forgot about it or they only had trail ski's.
The windshield???? no comments
So ya our new Viper is getting refitted, good thing Yamaha knows how to build engines otherwise it would be just another POS compared to the other builders.

I'm with Lund,
The Cat chassis is still 3rd in the mountains IMO and will be 4 model years old by 2015. I'm guessing Yami won't sell that many because of it.
Will it be an improvement over the Nytro MTX? Absolutely. I have driven the Viper and I like it. Hands down it performs better in trail trim or deep snow.
Is it better enough for me to trade in my MTX for a Viper MTX? Absolutely not.
Stock for stock, it would be an easy decision, but once you commit to changing a sled from stock to what you want (and many of us do), it gets muddy really fast. Everyone is getting much better at knowing what works to make a sled better for their riding style and it doesn't matter which brand you have. Some (yami) take more work, some (poo) take less, but some changes really narrow up the differences between sleds.
What Really kills me is that the concept of "evolution" doesn't seem to resonate with Yami. We all know the changes they made to the Nytro over its 7 year run we dismal at best (hand warmers and running boards...really???). There were some fundamental flaws that could have been changed to narrow the distance to the competition and they chose to ignore them. Rather, they chose to leave all the "REAL" improvements on the sled to the owners. No MTX-X or similar. Bad marketing choice that is and will hurt them in the long run
Basics:
Turbo - all elevations
Narrow the stance - Options, lots of options
HP - Get Nytro stock to 150 -155 and you will eliminate 50% of the Bit*hing (I know, I have one and its a different sled altogether)
Move weight down and back, and yes that includes cooling
Skis - Again...Give me Options width/length/keel and let me choose what works best for my conditions.
Evolve the platform....you know....add new bits!
Its crazy to me that the industry already has sold the buyer into the concept of spring order, x packages, dealer cost accessories, etc, etc, and we are still unable to customize a sled to any great extent.
Sooner or later one of the manufacturers will wake up and deliver...hopefully sooner, but until then, I think I'll keep the MTX just a bit longer.

OTM, what have you done to your engine to be 150-155 hp?

Full exhaust, K&Ns, and fuel programmer will get you there. I had that setup before the turbo and my sled ran hard.

That's what I am running...but not k&ns. I am doing the airbox mod. So theoretically the Nytro is 130hp....my kit supposedly adds 18.6hp bringing it to 148.6. I was wondering where else the 150 to even 155hp could come from...

There's also different spark plugs (can't remember which) that are good for a horsepower. There are dyno numbers on Ulmers website.

What they said 
It might be 145 HP, I don't know. What I do know is that everyone who has driven the sled all say the same thing.....it rips!
Honestly, my criteria is simple. I don't want it to feel under powered and it never does. Climbs really well (tho our climbs are short) and it can spin the track whenever I want, regardless of conditions or incline.
If I lived out west. I would turbo in a second.

Here is the weight comparisons between a viper MTX and a Nytro MTX.

Viper MTX was 550 wet
Nytro MTX was 584 wet

Good post, that is the same weight we got on the Viper, +/-5Lbs, we were closer to 545Lbs, not 550Lbs but that could had been the fluids differences.
But his Nytro weight is high, our Nytro did not weigh that much even with the turbo. Our's were approx. 545 without turbo and 570 with turbo.
To get 580+Lbs from that Nytro maybe he forgot his lunch inside hahaha
We have weighed a few Nytro's, never found one that heavy yet, but hey i guess there is one out there.
