I just finished my 05 tope end and took the bike out for some trail riding. An hour into it, I noticed the swing arm COVERED in oil. The sight glass on the oil side didn't read at all even with the bike tipped. What in name of all that is holy would cause the breather sytem to empty all the oil in the engine? Valves are brand new. We ended up pushing the bike 6 miles to the truck so we didn't seize it up. Anybody have any ideas? I have heard of a seal or something that goes out between the cases. Is there any other possiblity of why it would spew that much oil that quick. Thanks for the help guys.
