[QUOTE="jerryls, post: 814702, member: 49206"] The best mods you can do are: remove the buttplug from the muffler (even if its welded on), replace with a BMP insert (probably requiring some re-welding), open up the airbox, do the grey wire mod, and get the JD jetting kit. Just doing this should make a significant difference in how the bike runs. For more info, check out the WR250 forum at thumpertalk. Good luck! [/QUOTE]
