Description Our kit is the perfect, no fuss way to eliminate bike's factory air injection system. The factory system has several drawbacks including making it difficult to properly tune your bike. Drawbacks are due to the "fresh" air being injected into the exhaust causing O2 sensor readings to be incorrect. This modification also significantly reduces the ignition of fuel vapors (backfires)
