I've used it before on other applications and it worked ok. Its not that durable and tends to "crumble" when cutting it, or working it. Good for emergencies I guess.
I would purchase OEM gaskets for your blaster. The material that Yamaha uses has what looks like "long fibers" in it which makes it much more durable. The OEM gaskets are also very pliable.
Believe me when I say that you don't want air leeks around your reeds/intake, let alone anywhere.
Fel-Pro "Karropak" gasket material is pretty good stuff. You can find it at most automotive stores.
it comes in a few thicknesses.

On my blaster though, I would only use oem gaskets.
You say you have problems with your VForce reeds sealing? I've never had a problem. Are you sure your installing them correctly?
P.S. ... Don't use RTV goop to seal EVERYTHING, because of a warped sealing surface, or damaged gasket.
Don't be that guy.
