Heres a tough one... got oil leaking out of the ignition cover??? Why? I'm assuming it can not be a crank seal because the crank is lubricated by the pre mix, correct? Any help is appreciated.

You really need to pull off the cover, remove the flywheel and take a close look. It can be a crank seal and it does not depend on if the crank is lubed by premix or transmission fluid. You will probably easily tell if it's a seal as it will dribble down the case from the seal usually. Then again, it may be something else, like a leaking case gasket, and the oil will migrate to an area where it can be mistaken for a crank seal. You probably want to fix that before riding the bike anymore. Not quite so bad with a Pro as the trans fluid will go down but if it's a non-Pro engine, it will have an adverse effect on your jetting requirements and can lead to engine damage.

Hi DrHUD,

If it is a PRO and it isn't the crank seal as indicated previously, then it is possible that transmission oil is leaking out from one of the crank case allen bolts. At about the 2pm position behind the stator, this case bolt has a copper washer to seal off a drilled oil way passage, worth a look.
