When I try to get my Zx6R to redline (either in neutral or while driving) my throttle does not respond and sometime actually the RPMs decrease from the throttle position 75% to Wide Open. Any Ideas? I have a full Yosh RS5 exhaust and a PCIII. No FI Light. Also When I'm on the interstate in 6th gear I can only top out at 115 mph because of the limit of the throttle. PLEASE HELP.
