Hi all, my gf has a 1990 FZR1000, yes girl friend, & just a lil´ thing too!! lol Well whats up with this EXUP valve? I see you can wire it open but will it hurt the bike or performance in any way?? She rides it around town & every once in a while we take off on it for a few hours on the FWY together. Is this whats making noise under the bike?? HELP!!! THANK YOU in advance, Shawn
