Hello everybody l have just bought the air injection delete kit l am hoping to fit it to my 2017 euro4 b5 bullet after l have fitted the flow free silencer does anybody out there think l should fit it or maybe not l am also as well as the down pipe a gold star silencer from our hosts after the Easter holidays some people have said you need this to stop popping l do not know cheers all

Hi Charlie, the air injection delete kit helps to reduce the popping on overrun, particularly after fitting a freer flowing exhaust system over standard. The main benefit to me though, is to remove all the extra (ugly looking) pipework and solenoid around the head area and under the tank which the bike is fitted with as standard, the kit just tidy's all this area up.

I run my 2017 euro 4 bullet with a gold star silencer. straight thru front pipe and have fitted the air deletion kit, this kit does stop most of the popping and banging in the silencer on the over run,
