200 ES Severe Oil Leak

[aflaten]

Some info on the bike. I replaced the camshaft and pulse generator, put it back together it runs great, but oil is just pouring out of the pulse generator cover. I took it all apart and checked everything one more time, but it leaked again when i was done. My questions are, should there be oil getting in there at all? Do i just have a bad gasket or is it the seal on the pulse generator base?

Yes, there is a bigger rubber "o" ring on the back side of the pulse generator/cam cover. There should also be a gasket on the cdi cover. Im guessing the o ring is shot or missing. Not a hard replace at all. Good luck!
