I took the snorkel off my 2008 WR250Fs air box. It made a huge improvement!! It helped to get rid of bogging in the lower RPMs of higher gears. So far I've done all the "free mods"-- Grey wire, baffle removal, throttle stop removal, and snorkel removal. It's a completely different bike now, and none of it cost me anything! I was thinking about getting a FMF slip-on and re-jetting, but its running so good right now I'm not sure I wanna spend the money. I am thinking about getting hand guards- any suggestions?
