Where is the crank case vent in relation to the stain on the air filter?

Well, the vent is 180 degrees from the stain. The stain sits above the intake, which as far as I can tell pulls air from inside the case. (probably as a sort of conditioned air thing as there is no cold weather kit available.) So the incoming air obviously has dust in it, hence the filter, and the oil is saturated in the lower half of the filter so the dust gets trapped there in the oil - leaving the dark spot...and undoubtedly darkness from older oil.

When I run a towel into the filter grooves it comes out oily. Not sure if that is the way it should be or not. Overreacting?...possibly. All I know is it had never done this prior. She is running fine, no smoke, or at least none that makes me worry. It starts fine, the output is fine.
You know you are blowing my chances of convincing my wife we should have this:

I'll get another filter and see.


OK, I didn't realize that you cleaned the filter in the photo up, . . . . at least a little. It doesn't really look that bad. With that low of hours, there shouldn't be any oil dripping off the air filter or the foam seals on the ends of the filter. Find the crankcase breather and make sure its clear and that all the piping/venting is connected properly and flowing. Some Onan gennys had a TSB (technical service bulletin) to modify the breather, but, that shouldn't affect your model. (since it's a Yamaha) Are you using the correct oil and filling it to the proper level? (not overfull)

Interesting question as this has bothered me from day one. First I am using the correct oil but have never once been comfortable with how Yamaha describes in the manual to fill it. There is an image even of the oil coming all the way up to the last thread in the dipstick fill port. I asked the shop where I got it if this was correct and they said yes. I still think its a little bit too much. Or at least why they wouldn't have placed the dipstick port slightly higher. But I'm not an engineer, so what do I know?!

Nice to hear you feel the hours are low. I am really hoping I can get at least a couple thousand hours out of her. I know I have read people get long life out of them, but I run mine flat out for about an hour or two a few times a week for about 4 months out of the year.
I'm sure that doesn't do it any favours

Confusing statement about the oil level. Are you filling it by capacity or dipstick mark ? No matter what the place where you got it says, NEVER fill above dipstick level or you could get the problem you have

Hey RJ
Yah tell me about it!
I fill by the suggested volume +/- a tiny bit that I can't drain out.
The manual shows this:

Above is a perfect candidate for blowing oil all over the place !!
Some engines will tolerate it, some won't......trust me !
What the hell is the dipstick for.
