I’ve been making improvements to my Nytro for years, and recently made some vents/ filter housings that others may want to try. I made them with a woven mesh IN the plastic, and they will hold a foam filter as well. My intention is to add a pair to my dash, for goggle warming. My airbox lid...

After 3 seasons of testing, I may be ready to bring my own Nytro muffler to market for NEXT season. I built my own muffler from 100% stainless steel to be a direct replacement for the original muffler. It fits great, and uses the original plastics. Tone is nice, and NOT obnoxious at all. I...

Storage options for our Nytro sleds have always been hard to come by, so I decided to make a leather bag to fit in the nose of the sled. It’s bigger than the original tool pouch, and fits pretty well. I’d make a few more if there’s interest.

I’ll make this an install review, and follow up with a handling review afterwards. After searching high and low, I couldn’t find any mention of anyone who’s installed this Schmidt Brothers swaybar on a Nytro. Hopefully this helps others improve their trail handling. I’ve considerably...

My custom (home brew) muffler uncorked some power, but melted the cone in the exhaust cap. Seems to be a problem with other aftermarket exhausts, too. But I think I’ve got a solution that will work. Made this stainless steel piece to fit after trimming the melted plastic from the cover...

I touched on this in my Axys spindle post, but it’s worthy of its own topic. The stock FX Nytro 121 skid sucks. I was tired of getting beaten to death on rough trails keeping up with newer sleds, so I swapped a 120” RMotion skidoo suspension into my 08 Nytro. I already had Skinz Concept...

Anyone going to the Soo-500 this Saturday? I’ll be there, and solo trail riding Sunday. Most likely head to Mackinac Island.

So, I have this problem. When there’s no snow or time to ride, I can’t leave the sled alone. My Nytro has “suffered” at the hands of a fabricator/engineer. Now my dilemma. I have Skinz 42” arms, Float 2 shocks, RMK spindles, Fox Zero pro center shock, 1.5” 121 track, custom machined...

After seeing a few mentions of spindle swaps, and lack of good replacement Nytro spindles, I decided to try Polaris Axys RMK spindles on my sled. Hopefully this helps others. I chose to cut and reshape the bottom of the RMK part, and retain the use of my Yamaha ski rubber. Otherwise I...

Anyone have a blown up engine? I need a mock-up block to work with that has good mounting points.

Can anyone detail how to identify what year a Fx Nytro subframe is from? I've read that there are at least 3 variations, but no guide to identify. Thanks

I bought a 2008 Nytro recently with lots of aftermarket upgrades, and the owner claimed it had "a pipe". There was an MBRP decal on the tunnel, but the muffler appeared original. Didn't matter to me, so I bought it anyway. Now I'm going through the entire sled verifying it's ready for next...

Hi all, I'm leaning towards extending my Fx Nytro to 128" with rail extensions. I've seen that nearly everyone using the skid relocate or rail extensions has left the tunnel length alone. Looking at my 121 track, I see that the lugs are damaged a bit from hitting the tunnel protectors, and...
