I bought a ZR 580efi this fall and although the 121 track was great and all i wanted something i could take to the hills for a little boondocking. so i improvised. I bought a 144 track and made it fit. I also added a 2inch riser and a set of plastic skis from a skidoo rev. i bought the sled for 500 and i have put about 500 into it and put it together wit my own blood sweat and tears. I need some pointers on what a guy needs to do to make it mountain worthy. It is all stock as far as engine and gears go. it moves pretty damn fast as it sits too. i want to put on a 6 inch riser so i would like to know how difficult a throttle extention is too. i need to add some muscle to this beast both in the plains and up in the mountians the more performance tips the better gentlemen.
