Wow, I'm jealous. If you read on the forums youll find that a pipe and programmer turns the wr into a whole new machine. You can get rid of the AIS kit for under 20 dollars which will lighten up the bike. Also, the xup servo that runs the valve in your exhaust can be removed also with a sub plug. All this stuff is searchable and fairly easy to do. Really makes the bike a lot better. Also, shorter gearing is very cheap and makes a large difference. The WR has looooong gears stock.
