I was told that the moco Had upgraded gaskets for the rocker covers... does anyone know if that's true? If so,maybe there's some truth to a "better" gasket. Wondering also if I should should switch to cometic gaskets for the rocker covers on my evolution.

I have been down the leaking rocker box gasket road with an EVO. To the point that it ruined a trip I was on, because not matter what we did we could not get the gaskets to stay in place and ran oil all over the bike while going down the highway. I had to replace the rocker box, because it was warped and it hasn't leaked a drop since.

I'd venture to guess that what the OP is hearing about as a "leaking or seeping" primary is not from the gasket, but from the inner primary seal. That tends to weep and run down to the low point before dripping, and often looks like a gasket leak.

I admit that it isn't a sure fire solution, but it isn't total B.S.
He isn't asking about the derby cover gasket. He is asking about the primary gasket. There have been several cases where people noticed seeping soon after changing to syn in the primary.
Ypu can disassemble, clean and hone the surfaces, apply grease or gasket sealer, new gasket, torque to spec and it most likely won't seep. It is more work and more expense than just changing the type of oil. There really is no good reason to run syn in the primary and running thicker fluid may eliminate the seep.

unbelievable the ignorance of the american pampered public.....it, the gasket is just a barier between the the two metal surfaces, put some gasket sealer on one side, and some wheel bearing grease on the other, and you should have a well sealing gasket , that can be diasassembled with( care )in the future and used again......ride on......

It's a gasket. To bluntly answer your question, no there are not really any better gasket. Whatever the leaking problem is, the original quality of the gasket used probably wasn't the cause. I have never heard of anyone having a leaking primary problem because of the brand of gasket they used.
I've got some seepage from the primary cover and was planning a SE compensator upgrade and was only wondering if there were any better gaskets than replacement HD gaskets.
I have never worked on anything that has gaskets without having a replacement gasket just in case.
