I finally bit the bullet and picked up a Nytro FX. There was no reason to buy an RTX or SE model because they are basically a bunch of stuff I don't want to pay for, shocks and such. I like Ohlins when available, and the Ohlins rear skid shocks just arrived, so they'll get installed after a few break in runs on the stock machine. In all their gold glory...
If there is room I may try to install the Progressive Dampening System into these. I'm a big fan, as it work well. PDS is secondary shock inside the main body. It helps on the big hits...
More to come.....

These front shocks were to be installed on my Rage. Buuut, I think they'll work better on the Nytro. They are based on an Ohlins ATV shock and they already have the PDS installed. One of the major benefits to the PDS is being able to run the suspension a little softer, yet not bottom hard.

how much do ohlins cost? like the ones that were on the 40th ann. apex model? thinking of a 2010 black xtx for next year, depending if yamaha comes out with something new
They can be pricey, but are TOP notch. Please check my add in the classified section and/or PM for prices. FYI Ohlins, due to lack of market demand, will no longer be producing snowmobile shocks for new models, or stocking any of their current items on the shelf, and they are almost gone... They will all be custom order/build.
So as time permits I plan to mess around with the exhaust and engine on this sled. One of the first things I am looking at is swapping in the high flow header and couplers from my Rage. This is a project I started some 4 years back, but never really completed the R&D after building things. The old post is at this link...

So, the couplers and primary tube diameter on both the Gen 120 and Gen 130 engines are 35mm/1.37". One thing interesting about Gen 120 is that the exhaust ports are 38mm/1.50". Yet they feed the aforementioned 35mm/1.37 coupler. My speculation back then was they used the RX-1 couplers as they already existed, and didn't want the 120 making too much power. The Gen 130 port is 35mm, and matches the coupler. Where is this going? A full comparison of the old 120 head and new 130 heads might show some directions to take the 130 in to build more power. Larger ports are not always better, but it is curious that the lower power engine had slightly larger exhaust ports. Both engines respond to headers with larger than stock primary tubes.... fun times to come.
