You may have a cracked case. They can crack on the pinion side at the rear tranny mount boss. There's a thin area on that side and if the corner is machined square, rather than radiused, they tend to crack there... if they're going to.
I ride a 90, doesn't leak yet, would the torque arm prevent this or is it just in the machining? I was just about to scratch this post when I saw it was started in April until I looked at the last post date.

That's NOT a common problem, but the cases on some years were cast so very thin there, compared to the sprocket (left) side case. And some were machined deep and to a square corner under there. Certainly not something I'd ever worry about unless it leaked and even then, it'd have to drip regularly before I'd pull an engine for that.

Thanks for the feedback, been laid off for a couple months earlier this year, wasn't lookin to dole out money for this sort of thing.

Mine leaks really bad, so it seems. if riding the bike the oil gets all over the engine and tranny from the updraft. when i stop it looks like a hole is in the bottom of the egine. i clean it and just start the engine and let it idle on the lift. after a few minutes i can see oil run out of the area that t150evj pictured. I will bust the case this winter and see what i find. thanks t150evj for your assistance.
