Shifter cover leak

[Rat Rice]

I have an issue with my shifter cover leaking at the bottom of the cover. I've changed the gasket twice now. Yes the sealing surfaces are clean and dry. They're as flat as I can tell. I'm thinking about using case sealer to glue two gaskets together and seeing if that will fill the gap. Thoughts, suggestions, ideas??? She's not a old Harley and shouldn't be marking her spot every time I park her .

Cant be flat if its clean and dry or you are overtorquing the cover. Im guessing its not flat and has raised areas around the bolt holes on the gasket surface. Some cheap gaskets are also too thin, the oem honda gaskets have a little thickness to them, never had an oem one leak.

I used a straight edge and a feeler gauge to check flat of the cover, it's flat within.001. Yes there a very small bit of distortion around the bolt holes on the lower case. But the leak seems to be along the bottom of the cover at the center 3 bolts. The gasket I used I bought it on CB750, it does seem a bit thin compared to the "old" Honda gaskets. I don't and won't use RTV or any other "rubber" sealents as I've seen a couple of single cams torn up by a random piece getting in an oil galley. My thought is to use 2 of the gaskets that I just ordered from here and glueing them together and using that to fill what ever void there is. That should provide enough thickness compared to a stock gasket. Thoughts?
