I have a 1995 kx250 that recently discovered had a little coolant in the stator compartment. I pulled the stator off only to discover a slightly shredded o-ring on the taper of the crank. I didn't think much of it and just planned to replace it but I'm not even sure that it belongs there. I can't find an o-ring on any microfiche behind the stator. I'm starting to think that the guy that sold the bike to me put it there to slow the leak of a bad seal. Anyone want to shed some light? Thanks.
