2012 350/500 exc backfiring

Recommended Posts

Hey if anyone has a 2012 exc and it's backfiring and popping under deceleration, you can fix it by just plugging the larger diameter rubber line coming into the exhaust air valve on the right side of the bike. This is the intake feed line for the valve so plugging it keeps it from blowing the air into the port. No one knows this way. Don't remove anything as you could get a ticket.
