Just ran across this thread (I'm usually looking for KLR650 stuff on here since that's my bike, but I've got a 93 XT250 for the wife)
It is a great little bike and a blast to ride. Very fun to ride through the woods and so stinking light you can just about pick it up and move it whereever if you run into trouble. One of best mods I did was to disable the stupid "safety" switches for the clutch and kick stand. I was having trouble getting it started and it was because the clutch switch was bad. The other easy mod was to drill out the baffle. Someday I may get to the carb, coz this baby sure takes a while to warm up and run smooth, but when it does it's a blast. My wife is just learning to ride and likes it, but I think I've gotten a bit more seat time on it. I wouldn't trade my KLR for one, but as another bike to zip around on you can't beat it.
