Spark Arrester - Honda 450X 2005 Owner's Manual & Competition Handbook

Spark Arrester Inspection
The spark arrester must be serviced every 1,000
mi (1,600 km) of running or 100 operating hours
to maintain its efficiency.
Regular servicing prevents carbon buildup (which
can diminish engine performance) and also
complies with USDA regulations for regular
maintenance to assure proper function.
The spark arrester prevents random sparks from
the combustion process in your engine from
reaching the environment.
1. Allow the engine and muffler to cool.
2. Remove the four bolts (1), spark arrester (2),
