i just bought a nytro.its my first sled. i was told it was a mtx witch is what i was after.when i drove three hours to pick it up it was actually a rtx with the tunnel and skid off an mtx. it was a really good deal and only had 900 kms but know im wondering if i made the right decision in buying it. from what i can tell the ski stance is wider, lower bars, fox float shocks, different front suspension. is there any difference in the clutch or motor or skies that comes on this sled. to start i really want to get some kind of riser but i think i neet to get longer cables. any sudjestions on a height for mountain riding and a good kit or place to get parts other than yamaha dealer would be really appreciated. i plan on adding a roll over valve. theres a used timbersled front suspension with new bushings for 400 im wondering if i should buy it to narrow up the ski stance to help me tip this beast over.im also wanting a better trak after reading about this sled so i don't get left behind by all my friends who ride 800s. or should i just learn how to ride before i start upgrading things. thanks for any advice.
