On a standard exhaust this works as intended. However, when an aftermarket slip-on silencer or full race system is fitted, the additional airflow creates lean pulsing in the exhaust, resulting in sharp crackle, popping and misfires on the overrun — behaviour that undermines throttle feel and rider confidence on track.\u003c\/p\u003e\u003cp\u003eThe JetPrime JP ES 018 B blanking cover closes off the PAIR port permanently and cleanly, so the exhaust sees only combustion gases and the S1000RR can deliver the crisp, predictable throttle response your race setup demands.\u003c\/p\u003e\u003ch2\u003eRace Use — Important Notice\u003c\/h2\u003e\u003cp\u003eThis blanking cover is intended for race track use only and is not approved for use on public roads. Removing or disabling the secondary air injection system renders the motorcycle non-compliant with road emission regulations.
