2022 Kawasaki KX112 Exhaust System
Exhaust System
- The exhaust system, in particular the muffler body, is designed to reduce exhaust noise and conduct the exhaust gas away from the rider while minimizing power loss. If carbon has built up inside the muffler body, exhaust efficiency is reduced, causing engine performance to drop.
- If the expansion chamber and/or muffler body is badly damaged, dented, cracked or rusted, replace it. Replace the silencer wool and/or silencer joint rubber if the exhaust noise becomes too loud or engine performance drops.
