HI veryone I am a newbie to snowmobiling and just bought two new 09yamahas, a nytro MTX for me and an XTX for my wife. I've never ridin a mountain sled before and took my first ride last weekend. put on over a 100 miles it was awesome. I love the four stroke power and everyone we rode with was really impressed with the new sleds. Not being used to such a long sled I of course rolled lots. it seemed my MTX was really responsive and tippy. the XTX was awesome and super stable. I know i'm not used to the long sled and am new too riding but is there anything i can do to make it more stable and easier to balance especially when side hilling? I was thinking about getting some handle bar extensions and really need a left hand throttle. the skis seem to dart alot too how much difference would it make to get different skis? should just keep it stock til I get used to riding more or try and change some things?
