I've been reading a bunch of posts about WR mods and I've learned alot. I haven't really looked at a WR450 but here's what I'm trying to do... I want a YZ with a button. I'm thinking about buying the WR and trying to take off a bunch of weight, running YZ plastic, aftermarket exhaust, ect, ect...What issues will I run into?? Any idea what I can get this bike to weigh?? Give me an idea what you would do, and if you think this is a realistic idea. THANKS!
