    .2mm, .25, .4, .5 and .75.
    When the engine is assembled at the factory, the gasket or combination of gaskets that cause the X dim to = 0, are installed.
    There is no stock thickness gasket.

    My experience is that a .2mm AND a .4mm are often installed at the factory (for 250/300), but not on ALL engines.

    I hear you, but I prefer the KTM method. I'd rather be able to dial it in exactly.
