I read Lineaweaver's post regarding whether if rotax engines have one foot in the grave on flattrack.com. He mentions that ktm's cam will drop in a Husaberg. Has anyone taken ktm engine parts and tried them on a pre 2001 Berg? About a month ago, I took a ktm cylinder and sized it up on a Husaberg lower end. The fit was pretty much perfect, like it was made for it. The only difference I could notice, is that ktm uses a little larger dowel pins. I also interchanged ktm and Husaberg heads on both makes, and the proper fit seems to be there, other than a slight size difference in dowel pin size. On the ktm head, the cam seems to be shifted over to the left about a 1/4" more. I have noticed ktm top end parts are cheaper, and they have a better cooling system. I mainly checked this because of some ktm owners refusal to believe that their engine is a Husaberg copy. Plus, I was on the lookout for potentially cheaper and more plentiful blown engines parting out parts.
