Why Should You Repack The Dirt Bike Silencer

Packing materials around the muffler pipes help control the exhaust from engines. Once these materials get burned, the packing should be replaced after riding the dirt bike for 30 hours.

Usually, nobody changes their silencer packing ever…

For 2-stroke silencer packing, the packing gets old due to the unburned mix that exits from the cylinders. On 4-stroke silencer packing, it ages due to the high temperature that the dirt bike is producing. The bike will sound louder once the installed packing has been burnt. This may also cause a decrease in performance.

The silencer may break if the packing is used for a longer time. This would mean that you will have to buy a new silencer as well.
