They recommend repacking after 6–8 hours of use, or after each race. As packing becomes dirty, airflow from the motor can be restricted, which Yoshimura says leads to a loss of power and degradation of sound. Repacking replaces that material to allow freer airflow and help restore lost power while improving exhaust sound.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"trd-story trd-story--text\"\u003e\u003cdiv class=\"trd-story-copy\"\u003e\n\u003cp class=\"trd-label\"\u003eIncluded\u003c\/p\u003e\n\u003ch3 class=\"trd-story-title\"\u003eKit contents for service\u003c\/h3\u003e\n\u003cp class=\"trd-story-text\"\u003eThe RS-12 Premium Muffler Repack Kit 700G is assembled as a complete service solution for the repack procedure.
