Your bike isn't really stock with all that manSo I bought my '03 r6 this may and have had no issues with it until this.
Riding along and when you accelerate up to and beyond 9500 rpms there is a slight bog/lag/deadspot right between 9500 and 10k and up from there it takes some time to increase the rpms... Will only do it in 3,4,5,6 gear as I have tried to see/ feel it do it in 1st and 2nd but never can notice it there.
I replaced the plugs back in June and checked out the coils, seemed fine then. The bike is stock except for a PCIII, slip-on, and air filter. I recently cleaned the TPS (just because) but that was 5k ago.
