Bought an 05 WR450 and I figure I need a skid plate, rad guards, bark busters, WB E2 pipe and a JD kit. It doesn't look like I can put a different baffle in the pipe like my 03. Whats the deal with the air thingy on the carb? What is the best way to get rid of that mess? As soon as I sat on the 05 I knew I needed one. It feels like a YZ with lights.
