I have a 2004 GSXR 1000 (k4). It came with a Yoroshima exhaust (looks like it is just the silencer that is Yoro) and a Power Commander.
I went to download the correct map for the Half Yoroshima system and noticed that the notes on the map say "eliminates SET valve".
I'm a little confused. Does this mean the power commander itself eliminates the SET vale or is it saying I should disconnect it?
Cheers in advance
