Question about 2006 Bajaj Wave
I have just rebuilt my 1998 discover to replace a worn selector fork
Just a thought for you...On most Japanese bikes and fourwheelers etc... they do have the stators designed to be immersed in the crank oil. So there is usually a port, as you mentionned, and if you removed that stator cover, and tilted the bike to that side, most of that crankcase oil will seep through that equalizing port.
The oil does not harm the coils - the stator works on the concept of magnetism anyhow. The oil being in direct contact with the charge and lighting coils could help cool them down also. But the main reason there is oil in the stator is because if it's an electric start model, the starter gear is located in that same housing. The starter turns a idle gear which spins freely on the crankshaft. The hub of this gear fits inside the magneto (flywheel). Of course the magneto is fitted with a key slot so it's coupled to the crankshaft. So when this starter turns over, it causes the gear to lock into the magneto roller mechanism (or starter clutch) and then turns over the crankshaft. Once the engine is running, that same gear simply rotates freely and the starter is free from rotation. So the oil is necessary for the 'idle gear and crankshaft lubrication' as well as the 'idle gear to magneto roller mechanism (starter clutch)'. It makes it a pretty compact design doesn't it.

Which seems to have solved the problem I had with the bike jumping out of 5th gear. Now on the not-so-good side. I now seem to have very high pressure in the crankcase enough to spray oil out of the channel that links the generator (rotor) area with the gearbox and coats the rotor and stator with oil. Its as if the oil isn't being picked up properly or maybe if the oil runs through one of the gearbox shafts - do I have to align the oil feed hole in this with something? This was the one thing that I wasn't certain about when I rebuilt the gearbox.... would this cause the problem? I can't find any crankcase breathers that could be blocked so I assume the bottom end vents up the channel for the timing chain, and then out the top camshaft cover and the thick black pipe on the top (which is clear). ,Either you have excess blowby or a passage somewhere is blocked. Leak down test first, then its back to removing covers until you find whats blocked,,,
