Over time, dirty packing can restrict airflow from the motor, which the manufacturer says can cause a loss of power and a degradation of sound. Repacking at the suggested intervals helps return the muffler to freer airflow, restoring lost power and improving the 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\"\u003eMaterials\u003c\/p\u003e\n\u003ch3 class=\"trd-story-title\"\u003eWhat’s in the kit\u003c\/h3\u003e\n\u003cp class=\"trd-story-text\"\u003eThis RS-12 series repack kit is supplied as a complete set of service items: premium packing material, rivets, a rivet band, decals for the muffler sleeve and end-cap, and repacking instructions.
