When installing an aftermarket exhaust on your Yamaha WR250R/X, the AIS (Air Induction System) is no longer serving any purpose and will cause backfiring/popping on deceleration. Once you remove the AIS from the bike, this kit can be used to block off the port/hose on the bike. Full instructions, with photos, is included.
