Up to this time I have never owned nor built a 4 stroke snowmobile. Everything has been geared to riding 2 strokes for flat land, and also mountain sledding. You just can't beat the quick response of a 2 stroke sled, but in the same token I cannot deal with the immediate depreciation you get when you own a 2 stroke sled. Let's face it, how many 2 stroke atv's, side by sides, or even cars to you see motoring around these days, enough said!
So, many may think I have come over to the dark side, but 4 stroke sleds are the future of sledding and they are here to stay. Not only do they hold their resale value, but they are also better for the environment too. Yes you have to deal with the extra weight, but the installation of the turbo should help off set the weight some, and give us plenty of grunt to tackle almost any hill that I am brave enough to climb. The stock turbo set up is rated at 180hp, but we have some plans to take this motor to the 270+ HP range very soon. My master sled mechanic and good friend Mark Leipheimer from Leipheimer Yamaha in Butte Montana has been working on these Yamaha sleds for many years. He is no stranger to working on Turbo-ed Snowmobiles, Mark is the MCXpress Snowmobile Turbo Distributor for the USA.
Some of the issues we have experienced with the Yamaha MTX Nytro Mountain sled version are, claimed heavy weight (mainly because of the 4 stroke engine), poor handling (steering geometry is off somewhat for effective side hilling), poor range(small 7.4 gallon gas tank), and lack of power. You would think that this would deter someone from riding this style of sled, but not to worry this a challenge that we are up to!
First of all the Turbo should fix that lack of power, and should help to haul that extra weight across the snow. I guess I can shed a few pounds, so that might help the weight issue some, right :). We can install a larger gas tank or just carry some extra gas to help with more effective range in the mountains. We will change up the ski's to give us better flotation and handling, plus we will install an aftermarket a-arm kit that will help us with easier side hilling, and better carving.
So, we have our work cut out for us, and I look forward to getting into this project build. I hope you join us and follow along as The Montana & Wyoming boys do some modifications to this Yamaha MTX Nytro 162 sled.
Editor Note:Product Recycling
If you have followed some of our other ATV,UTV, & snowmobile projects,you will notice that we use a lot of the products over and over again on different projects. Some of these products blend in well to almost any type of outdoor recreation, and we make good use of all the products we get from the manufacturers.
In this project we have used Holz racks, gas cans, and ice scratchers from a different sled build. As you can see they work great on this build.
We have been using Snobunje products for years and find them to be totally reliable. You may not see it but we have all the Snobunje towing gear in the Snobunje bags on board our sled.
Amongst our PowerMadd products are the hand-guards and mounts from one of our previous sled builds.
Our camera and the gps we use are held in place by the tried and true Ram Mounts that have been on everything from out motorcycle ride reviews to our atv reviews and so on. Ram mounts work and are bullet proof.
Our back packs are by BCA and we have used them to carry our gear on every occasion. I have not been able to kill one of these bags, and I trust them to carry my camera gear and essentials safely.
All our sledding gear is by Kimpex/CKX and is the only gear I use for sledding.
As you can see we like to recycle here at ATVPT.com headquarters. So bare in mind the next time you purchase something for your recreation vehicle, think about what other uses you may have for this product.
My first test ride of the 2012 Yamaha Nytro Turbo sled with most of the major modifications finished. But wait, there is more coming..........
Currently looking for an AVI Air Bag that will accommodate not only shovel, probe, essential AVI Safety gear, but also carry our camera equipment as well. I will take suggestions from any Avalanche Air bag Manufacturer.
Ideal bag would be from 20 to 30 + liters in capacity.
