Okay, so my screen name is a bit preemptive given that I havn't purchased my thumper yet. I'll give you that. I'm looking at a '99 WR400 with a header pipe, W.B. exhaust, shock & fork revalve, IMS tank, and some extras. Some plastic has been replaced. There are more hours on this bike than the '00. The '00 just has an FMF exhaust. The carb slide stop has been opened up. Fewer hours. There is a $500 difference in asking price. Both have said they will accept less than asking price. I plan on putting on a Baja Designs kit to legalize it. Question 1: What would you guys go with? Question 2: Does the hot start feature make a big difference? Question 3: What's the story with the "grey wire" cutting? Any advice will help out bigtime. I'm a WR idiot I guess. Pretty experienced on other bikes though, mostly 2-strokes on the track. Throw me a bone here boyz.
