I have an '04 WR 450 that I bought last year. It's my first bike in about 10 years. I'm a bigger guy (270 lbs) so I went with the bigger bike. After the first few rides, I uncorked the exhaust and cut the throttle stop screw to YZ length and I've been riding this way ever since and have put about 300 miles on it. I'm realizing that this bike is a LOT of bike and was considering trading in on an '05 WR 250. After talking to a few dealers, though, it's not a very good thing to do financially (one dealer wanted me to pay $300 more for a '05 250 than I paid for my '04 450 brand new! ) Does anyone have any suggestions on making the 450 an easier bike to ride in trails? I'm in WA so I ride mostly woods. Would adding a tooth or two to the rear sprocket be any help? How about a new top triple clamp and bars to change the steering feel? What about suspension setup? Are there any ways to make the bike a little more ridable so I'm not completely beat after an hour long ride? My buddy on his CR250F can ride all day and not feel winded...'course he's in better shape than me and there's no substitute for working out, which I begin again Monday.
