What would cause your transmission fliud to end up mixed in your engine oil after riding your bike?
One way is your counter shaft seal giving out
Thanks. Does that have anything to do with the counter balancer?
search "oil migration".. lots of threads on this, the right side crank seal is out if the trans oil is migrating to the engine side. been there myself. trans oil level goes down, engine side goes way up and actually pukes out breather tubes at some point if bad enough.. get the updated double lip seal, follow instructions for replacing. No need to split cases or anything, but the clutch cover, entire clutch, etc. have to be removed. if engine oil is migrating the other way.. it's somethin else (haven't had it happen yet), but threads on that too.
Have you ever pulled off a clutch, or primary gear? This work is quite easy but if you've not done it before we can give you some good tips!
