It's a 2005 NOT a 2006. I screwed up with the title. I've been talking with a guy who has a 2005 KTM 950 with 20,250 miles for sale. It is real nice and runs good at normal speeds and RPM's BUT at about 6 grand the engine starts vibrating hard. Also, if you cut it off then start it back up a few minutes later, the engine sounds starved for oil for about 2 seconds. I didn't get to hear it start up when it was cold as I was filling out a waver while one of the employee's started it. I made a video. You can just hear the clatter for a brief second or two. If you restart immediately it wont do it. <iframe src="http://www.youtube.com/embed/r9Z_CbYUUlI" allowfullscreen="" width="420" frameborder="0" height="315"></iframe> Do you think this is normal? I know BMW's do this but have never heard of a KTM doing it. A buddy who has a 990 said his does not do this. It's a real good deal(that I've been negotiating) but I don't want to be doing engine work right off the bat if there is something wrong with it. Any suggestions as to what might be causing it? Causes, cures? Should I get it or walk away?
