Well, I think i done it. a 2003 400ex with a WB pipe, k&n jets, and the WB filter. I was riding like usual, and everyhting fine. Then after a days ride, I get hardcore bogging out on high RPMs. Like bogging and losing power. I figure its a dirty airfilter, so I change that. No change. I think because I took out all the discs and back plate on the exhaust. I figured there wouldnt be a problems because it didnt seem to be running lean. Any help?
