Just secured a new '05 WR450...been dual sporting a KLR for a couple of years, and wanted a real dirtbike! I know there are some simple mods that are typically made to the WR450...my dealer tells me he removed the throttle stop already - how would I know? Also, I've heard something about a grey wire? What's with that? I've put about 100 easy miles on it...the engine seems to be breaking in and revving more freely and has plenty of power for my limited dirt riding skills! I've installed the ProBend hand guards, Flatland skid guard, and TrailTech computer, and plan to install the Flatland radiator guards (yes, I expect to fall down occasionally). What's next guys? Offer your wisdom to a newbie WR450 owner!
