My 2007 KTM 450 XC decided to be evil. After the first ride after some maintenance, the rear of the bike was coated in oil. I cleaned the bike, did a full oil change and it still leaks. The oil leaks out of the port featured in this internet photo: http://www.flickr.com/photos/34523749@N08/5456209115/lightbox/ The last things that I did to it was: - Remove the clutch cover, remove the clutch basket, drill holes in the clutch basket to allow for more oil flow to eliminate the 1st gear clutch chatter) - replace the countershaft seals, o-rings and spacers. When I replaced the countershaft parts, I may have overfilled the oil. I cannot find that port on any of the fiche. It doesn't appear to be threaded.
