Yamaha XT550 oil in CDI rotor side

[ColinH]

Hi All, been struggling with starting the XT550. The spark is quite weak so I went to look at the CDI rotor side of the engine. When I removed the side casing, all the engine oil poured out. Should there be oil in there? If not, do I have a failed crankshaft seal?
Thanks for any help.......

Was there a gasket there? If so, the oil is probably supposed to be in there....

There was a gasket......

Would a pic kill ya?
Anyway I reckon the gasket is just to prevent dust water ingress and it shouldn't be bathed in oil so the crank oil seal sound like its not a seal any more

Something is not letting me attach a pic.......
Thanks anyway, to my mind it should all be dry in that side.
I’ll pull the rotor and see where the oil is getting in.

My XT660 derived bike had a wet alternator so I'd expect the 550 to have one too.

Most modern Japanese bikes have a wet alternator.

Thanks everyone! HT lead, coil, plug cap, plug all new.
I think it must be designed to be wet. When I leaned the bike over to the left another load of oil spilled out very quickly - I guess the remains that were in the bottom of the crankcase. If it was a seal gone, it would have just dribbled out......

On reflection, I had it wrong it does run in oil.
Not sure what I was thinking of, probly a variator
now I is a scooty boi

Anyroadup shouldn't resistance tests be the the first step in
determining if the health of the stator/pulser?

Withe electronic ignition generally anything pulse side of the cdi or tdi either works or doesn't work. It's the lt/ht side that generally causes a weak spark.
