I rode a WR with a YZ seat/tank and liked it a lot better than my stock tank for sure. I have never ran my WR out of gas but I am wondering what kind of range should I expect with the smaller tank. Can you do a 2hr eastern hare scrambles or will you have to pit for fuel. That will make my decision. How have you guys made out with the YZ seat and IMS or Clarke tank? Do they look OK. SOme guy in the DRZ forum said his IMS tank kind of sucked. Thanks!!
