Large hole.   Note: Steel breathers require steel breather valve spacers. Plastic breathers require plastic spacers. Do not intermix steel and plastic parts.  Note: The OEM plastic breather is low cost but an inferior; poor quality product that will cause damage to crankcases in the breather bore since it is prone to distorting. The sooner this stock type breather is removed; the better. We highly recommended to replace it with a steel breather valve; like was used in earlier engines.\u003c\/p\u003e\u003cp\u003eL77-99 Big Twin (Excl.
