hey yall. Im building a 2005 rm250 that I picked up for 1000 bucks. I just got my cylinder back from Eric Gorr and the gasket kit looks like this. Is this normal to have the gasket a circle instead of following around the intake?

and yes...that is the proper gasket

I would be tempted to cut to match cases, but I wouldn't. If it was causing problems, they would have revised the part.

The other thing is using a gasket to restrict flow, seems rinky dink to me and like a weak link, those gaskets must be tough sob's !!
That friction is resistance, resistance + flow = system pressure. If you increase your volume over time (GPM) where resistance does not change, pressure goes up.
So the prime mover (motor) basically provides variable displacement because of RPM is variable.
My guess those holes regulate system pressure at idle. A gasket can be changed easy, so making low idle pressure adjustable.
