I've had my 2008 WR450F for 6 days now. I love it! My last big bore was a new 1988 510 Husky desert model. Just as I got to the point where I could ride it in competition, I had the misfortune of hitting a cement culvert at 100 MPH and broke both femurs and crushed my right forearm. 14 hours of surgery and 2 years of rehab, caused me to stay away from dirt... until now. In stock form, this bike has enough giddy up to make me smile! I'm 6' 4" and 280# and it hauls my butt around just fine. When I get to the point where I can dog it in stock form, I'll unplug it. I'm looking forward to it! Anyway, I have five acres of land to ride on, and no, its not nearly enough for this baby. While making a new trail today, I was working my way between some small trees when I got a whiff of something burning. I stopped, looked down and to my surprise, I see a large leaf laying on the header pipe smoldering. Then, it burst into flames! The sight of an open flame underneath two gallons of premium in a plastic container attached to a $7,000 motorcycle between my legs kind of freaked me out a bit. So I reached down and knocked it off. Whew, bike fire averted. The now flaming leaf fell into many years worth of other dried leaves and started a small fire. Now, I'm about to drop the bike in my rush getting off, shutting down and moving it away from the impending forest fire. I finally got it all stomped out. What a day. I may wrap the header in that wrap stuff to prevent this in the future. I just wanted to give all the other WR riders a heads up to keep an eye out for this when riding in an area with a lot of dead leaves. Thanks to all of you for providing much needed info on this great bike.
