So yesterday as I was doing a valve adjustment, my buddy set a rubber washer on my tank, by some act of God it fell off and INTO the open spark plug hole. We then spent the night pulling the engine. The engine is in great running condition with the exception of what i think is a bad valve seat on one cylinder (getting oil in the exhaust). I am planning on hardtailing the bike and wanted to take care of the valve issue anyway so its no big deal, but i'm wondering if there's a way to get this washer out without pulling the hole thing apart to get at it. It is sitting on top of the piston as we speak.
