I can't imagine why anybody would do this other than just kinda fun or whatever. If you like the blast, but just want it to have a little more power, then maybe clutch weights maybe gear down. If you like the blast but want it to have quite a bit more power, then the Polaris 650 146 Khaos Slash is unquestionably the perfect sled to move up to.Seeing that factory boost is becoming a thing, what do you think a Blast Limited would be like on pump gas boost? Might be a little much for new kiddos, but I feel like it would be a sweet wife/GF machine.
