I just bought a 2005 WR450 today. Very excited. This is my first bike since I was a kid. I thought about getting the 250, but came across this 450 and it was a good deal. The guy bought it new in 2006 and had it out 4 times for a total of 138miles. And the odometer shows 138. He said he didn't ride it so there was no need to keep it. Blue book on this bike is $4300. I paid $3500 and got a stand, ramp, all his tie downs, and a service manual. He said the dealer did the gray wire mod, but he was unsure what else was done. I have yet to look into it to see what has been done. I plan on all the free mods and to take all the baffles out of the muffler and get the promoto setup. This bike started right up with the e-start when the bike was cold and an ambient air temp of about 70f. Also, it kicked over in one kick after warming up. I got it home tonight and the temp was close to freezing and it had been in the back of my truck for 4 hours... it didn't want to start at all. The battery drained and I had to kick start it. But once warm it was ok again. I had ridden a 2000 WR400 (with the 426 engine) and it didn't seem all that fast. I was actually very disappointed. The 450 is a whole different story (in the 400's defense it was poorly jetted and bogged horribly). I test rode the 450 and it pulled wheelies in the first three gears. The power delivery is very smooth compared to the wr400/426 I rode. Here are some pics: Here is a clip of the exhaust idling. it's 14mb. http://www.3.8mustang.com/justang/WR450/MVI_1486.AVI Does this sound stock? Or could there be a baffle removed? It sounded louder than I thought a stock bike would. I need to learn about tuning this bike properly using jetting and the fuel knob. My night will be spent searching TT. I plan on changing the oil tomorrow and going through it to make sure it's up to date with it's maintenance. I'm sure it is, but I want to "zero out" everything so I know when it has to be done again. I'm very excited and can't wait to ride it more. The power from this bike is... Yeah, my garage is carpeted.
