My F800GS with about 7,000 miles at the time developed a minor oil leak while thrashing it around Moab. Carefully watching the oil levels, 2 days later I got it to a dealer, and while they were "fixing" it, more than one tech was standing around my bike looking at the cam, and what appears to be chunks of metal missing from it. I would like to hear your thoughts, especially if you have some first hand knowledge about cams on an f800 or similar Rotax engine. I believe that it was made this way, and didn't break off in the engine. I've changed the oil 3 times myself and there's been no debris on the magnetic plug. I was told this is normal, and was done in the casting process. :huh It still doesn't look right, so I figured I's ask the experts. BTW, a cause for the oil leak was not found, according to the dealer the head was torqued correctly and there was nothing wrong with the gasket... they added some liquid gasket to it and it hasn't leaked. First started leaking oil at the nearest (open) dealer in the direction I was heading The Cam... all of them had a chunk missing kind of close to the lobe.
