I've just purchased an 03' WR450 with few hours on it. What mods/set-up should I be looking at? I have always owned CR's and KTM's, so the Yamaha is something new for me. I know the woodruff key issue has been done, suspension done by RG3 and the spark arrestor insert has been changed/modified. Is there anything else I need to watch out for (jetting, etc). Also. is there a quick fix for the brake routing to get brakes on par w/ the CR? Thanks!
