How to Repack a Silencer

A silencer is a device that is attached to an exhaust system and used to reduce noise. The benefit of repacking silencers goes far beyond lessening the noise that is created by the engine. Regularly repacking your silencer will ensure that your motor consistently gives you maximum power. It will also extend the useful life of your engine by years. Silencers on dirt bikes should be repacked every couple of years. Silencers are not unlike mufflers.
