I can't beleive what I'am reading here, because a few bikes have sheared the woodruff key and the jetings off, some of you are saying your thinking getting something else because of "all the problems" give me a break. all you have to do is rejett which is something you usally do anyway if you get a after market pipe or live in a higner altitude. and tighten your magneto nut , big deal! I can garuantee you will have more maintainace hassles with the euro bikes than you will with the WR's. don't get me wrong the KTM's are great bikes, there light, fast, handle great, but like any high strung race bike, they require at lot of maintainace. I guess I just don't see the worry some of you are having. Since I have jetted my Wr450 it starts easy, runs perfect & handles like a dream. Com'on guys I've had to rejett almost every bike i've had, cause I live at 4500 ft. funny it does'nt bother you to rejett when you buy a new pipe, but it bothers you to rejett to make run and start better.
