What's this hole in my transmission case?

[Ola]

I swear I saw someone ask this question once, but couldn't find it with search. I also can't believe I've never seen it before, which leads me to believe there was a bolt or a plastic plug in here.

You're looking at the sprocket cover in the lower right corner, starter cover lower left.





It was too late and dark to begin taking the sprocket cover off, I hope the hole ends up in there and not in my gearbox. I'm having a waking nightmare of all that dirt and grime falling into my transmission. It's a bit cleaner now than it looks in the pics though, doing some carb work at the moment.

That is a drain hole to drain water or fuel that builds up on top of the case. It exits under the sprocket cover. No big deal. Dar

THANK YOU I can sleep well now. I'll also nix all ideas about blocking it.

Nope, clean it out instead

Sounds like another version of the famed Mystery Hole.

Also, it helps a lot if you reveal what sort of GS you're asking questions about. They're not all the same...

Pretty funny to come across this thread...I had the same horrific visions one day last summer. Im out in the driveway washing the bike and just happened to look down and see the water going into the "mystery hole".....my first reaction was "Oh sh%t !...where did that hole come from??? and where is hell is that water GOING ???!!!

Haha that's funny, another victim to the myth I suppose. You're right about bike info, I added it to my signature.
