Product Description

Our blockoff plates will stop the annoying and possibly damaging
backfires from occurring while allowing you to remove a few pounds in
associated valves and hoses from your bike. On late model EFI bikes with
02 sensors, ESPECIALLY when using Dynojet's Power Commander V with the
Autotune feature, the air injection system MUST be blocked as it will
introduce additional oxygen into the system which will skew your 02
sensor's values and make it impossible to get a correct tune.
