I have a 2004 ski doo mxz 800 rev and it is just too hard on gas. I want a fast sled that wont take up a lot of fuel and one that is light. I have reveiwed the phazer and it is a overall nice machine but it is lony 80 hp. I dont know if that will be fast enough for me. I have heard that you can put street bike pipes on there but i dont know if that is true. i would like to get a supercharer or a turbocharer if i need one. pleae leave some sites for some performance parts. I have also reveiwed the nytro which I know would be fast enouh but it is kinda heavy.
