Hello all. Been doing a bunch of research but can't seem to find much. I have seen where people mod there exup valve to stay open at all times on other bikes, but can't find much on the FZ. I did find one thread where someone did this and didn't notice any negative effects. Curious if anyone has experience with this or knows of any negative effects. This would be done on the stock ecu settings. My only reason for doing this is to potentially gain some exhaust volume in the lower rpm's while saving for a 3/4 system.
