I have read that the KTM 2005 was detuned from the 2004. Is there anyone in the forum who could tell me the differences in tunning between these two year models. I think it may have plenty to do with cylinder port timing. If anyone has a 2004 0r 2006 cylinder and could let me know the dimensions from the top of the exhaust and transfer ports to the top edge of the bore it would be greatly appreciatted.
