250-500cc WR300 powervalve gasket.

Hi, i have just rebuilt the top end of my WR300 2010.
(plated cylinder, ajusted and slightly ported cylinder, race head with squish mod)

There is no gasket or liquid gasket to seal the front powervalve cover is this normal ???
Only the small o-ring for the front prestone hoose but no liquid gasket or gasket ???


Thanks

I was also curious about this. One of the first times I started the bike I noticed a little puff of blue smoke coming from the right side power valve cover. Just a tiny little bit. It doesn't look like there's a gasket on mine. Haven't taken anything apart to prove that or see what's under there. Yet.

The right and left powervalve cover have gasket, but the front dont seem to have one.
