I've got the IMS on my bike. Had to do some re-molding around the radiators with the heat gun and on the nub on the bottom of the seat. There's a gap between the edge of the seat and the tank that doesn;t look so good. But it does what it's supposed to, hold gas. You'll need to buy some new fuel line to as the petcock is on the other side.
