I have a 2007 ZX6R. I have power comander and two brothers pipe. Has been tuned with pipe and racers trick. I was running 112 octane and switched over to 91 octane (not by choice) Then i pulled out of the gas station and tried to get on it to race another zx6r that was stock. My bike acted like it had flat spots on accel and the at the next light was smoking light i lost some rings
. So i told my self i was going to limp home but the smoke cleared out at the next light and the bike is running good now. Any thoughts
