Riva single intake manifold ?

[yamanube]

I purchased a new, second hand riva intake mani and adapter plate. It came with everything but the manifold/reeds to case gasket. On the OEM setup there was a gasket, a thin plate and a gasket between the manifold and the reeds, this also acted as the gasket for the manifold to case sealant. On the riva setup do I just use one gasket or do I put the whole setup in there?

just one gasket, you will have to trim it to fit.

Don't use the thin plate from the OEM setup.
