I know this is going to sound childish and it is childish I suppose but here we go! I own a 2014 HP4 and it?s brillant however. I have had a shot of a 2015 s1000rr and can?t get enough of pop and bang it does every time you crack the throttle slightly. Iv done a bit of research and it?s the air injection into the exhaust that makes the bang. The part number for the air injection valve is the same for gen 2 and gen 3 so is it ecu controlled or am I missing something?
Thanks in advance Jordan
