79 GS850 Oil Leak - WTH?

[Goose]

Ok, darnit, I've got someone interested in the 850 and the bike decides to spring a leak on me. I figured out where it's coming from but I have no idea why. Behind the secondary cover, there's a hole about three eighth's inch in diameter. Doesn't seem to be a threaded hole. Seems like it is what its doing, a weep hole of some sort. Any idea what this is and why there's clean oil oozing from it? The hole faces downward. Here's a pic:

That is the mystery hole. Most likely the O ring on the starter is bad/leaking thru the drain hole in the engine

Ah, the "mystery hole"... I feel SO much better... Seriously, that makes sense. And if it is the O-ring on the starter, that wouldn't be such a bad repair. I'll have to tear into it tomorrow after work.

Thanks, Lynn!

Wow. Once again, I find myself humbled by the amount of knowledge on this site. From the pics, looks like it could be either the o-ring on the starter or the gasket on the oil pressure switch... There is a gasket there isn't there?

You guys are great. Thanks SO much.

There is an "O" ring under the oil pressure switch, Part No. 16448-45000 and to remove the starter motor to replace that "O" ring you will have to remove the carbs first to get at it.

I was hoping to get the starter out without removing the carbs. Pretty sure I was able to do that on the 550 when I had to replace the starter, but it was a little different bike than the 850.

Thanks!

If you could remove the starter from a 550 without pulling carbs then the 850 would be a breeze! I can't get my hand under the carbs on my 550 to adjust idle let alone remove starter cover.

and you can remove the starter from an 11 without removing the carbs....

About that starter O-ring, is it Part #13 in figure no.22, BikeBandit PN- 1028626?

And is there a walk-through on replacement posted anywhere?

Thanks for the help, ya'll
