I have an 07 ZX10, The only performance mods are my Two brothers Single side exhaust. It does it at all temps outside, and if the bike is warm or hot. I pulled the tre off thinking that was causing it, didn't fix it. Changed the spark plugs and that didn't change it either. At high rpm around 11k the bike will cut out as if someone is turning the key off and on. I can't seem to figure out what it is. Oh, I also checked the tilt sensor and the kickstand switch and it still does it. Any help is greatly appreciated.
