    Contact lenses?

    I wore contacts for about 20 years, got lasik surgery about 8 years ago and it was the best thing I ever did. I wish I would have done lasik surgery sooner. Worth every penny.

    SR Viper MTX turbo clutching!

    Close, slight primary spring change yet, but weight settings remained the same. Good deal. I think I would be happy with that setup that we rode, that's great that you improved on it. The snow has been very good this year, for April riding it was great last weekend.

    SR Viper MTX turbo clutching!

    They were in the Snowy Range WY. Allen - I met your crew on Saturday morning and they (Jeff?) had just put a new setup on the blue/orange turbo LE. Cody let me take it for a quick rip before they went out riding for the ride that day. How close was that setup to what you guys ended up...

    MTX

    Get the 162 - the added floatation will be more forgiving. I rode stock 4 strokes in the mountains for a long time before my turbo. You won't be highmarking anyone, but a good rider can boondock them anywhere the other guys go.

    New Supercharger

    Do a google search for MPI supercharger install - there is a guy on another forum that did a step by step install and took pictures of everything. That should be everything you need.

    Can't get 8 lbs - Nytro 180 kit

    What elevation? I am seeing 8-9 lbs at 10-11,000 feet. I think the easiest place to start looking would be the blowoff/bypass and go from there.

    2015 Viper Mountain Demo Ride

    X2 The XMs that I ride with (2 boosted and 2 that are stock) are a blast - and have been very reliable. I'm not ready to give up my pump gas turbo for one of those aero chargers just yet though. I still like the 4 stroke turbo better for the riding I do.

    Skinz A Arms and Running Boards

    I am on my third season running both the air-frames and the a-arms on my MTX No complaints at all on the air frames, worth every penny IMO. I ride with guys that own all brands - the air frames work better than any stock or aftermarket boards in our group. I had the early version of the...

    Koso gauge install (boost, a/f, temp)

    I have the Koso boost only guage on my nytro and it has worked great. Some info on the one you bought on this thread - but not much about the install itself http://www.snowest.com/forum/showthread.php?t=366674

    2015 Mountain Vipers

    That is Mark's sled and his rig - he is the MCX dealer out of Montana and probably has quite a few miles on his own sled :)

    Do we care they killed the Nytro?

    That turbo deal is not "new". My 2012 snowcheck MPI turbo was $1500. That was the only reason why I bought the sled, it was a great deal on the turbo IMO. tk

    Do we care they killed the Nytro?

    A lot of the things I did to my 2012 are "standard" on the 2015. (same things everyone has been doing for the last few years - OFT relocator to get steering more vertical, airframe boards to evac snow, skinz a-arms to improve handling, etc.) I am curious on a couple things - how are they...

    Nytro MTX skid changes, 2008-2010?

    A guy is parting a 2011 out over on snowest - I will PM you the link to the thread.

    Nytro MTX skid changes, 2008-2010?

    2010 was the first year with the new skid on the Nytro - it is a pretty good improvement over the 2008. If you can get a deal on the 2008 you can look for a used skid or put a Cat skid under it as well. Lots of options.

    Center of gravity

    I think a lower CG is great for trails and flat cornering, but doesn't matter quite as much for off trail riding, it helps though. For off trail riding I think a sled that has the weight balanced equally (front to back and left to right) is equally important. Obviously you don't want the CG...

    2015 YAMAHA SNOWMOBILES

    for the high elevation guys 165 NA HP isn't going to be enough unless they do the 75-100lb weight drop. at 10k feet we lose 30% of our HP.

    2 gallon rotopax?!? Anyone have one?

    Not needed from what my dealer told me. I have two seasons with my setup and it is holding up fine so far.

    MPI sells a stage 1 upgrade kit for the 180 kits. Both are around $1,000.
