I need to rejet my 2007 400 ex. looking at my carbeurator it looks very tight to get to. can anyone please tell me if I need to take it off the bike to do this? or can I rejet it without having to take bike apart? Please list the steps again for me to follow. (im so pissed off, i rolled my bike yesterday with my new fat bars on for the first ride and bent the steering stem plate on left side and now the bars are uneven) Any advice on how to fix that too? greatly appreciated!
