  • Sounds like second gear is bad in your transmission

  • Hard to imagine it being something else when it's only happening in second gear and it's consistent

  • But why only when i hit 6k rpms

  • I think you'll get that answer once you zero in on the issue

  • Do you have any mods that affect your ignition timing or a power commander?

  • Because its only happening in second gear I am stumped!

  • You may find some answers here?, did you change exhausts?

  • I don't have a clue really

  • If its only happening in second gear.., you wouldnt spend long in second gear any way.

  • Certainly not at 7000rpm.

  • By 7000rpm you are horsing her on :-p

  • By 7000rpm i'd be wanting to shift to 3rd.

  • Allan MacDonald you any ideas?

  • Was thinking fuel pump myself

  • Allan MacDonald , but only in second gear and at 7000rpm?

  • Surly in second gear and at 7000rpm she would be screaming the guts out of herself?

  • ZX12R just waking up at 7 Grand

  • Allan MacDonald , Been a year from I have ridden :-/

  • But never focused much on the rev counter, just keeping the front wheel down :-p

  • Well compared to a 14 anyway

  • I was thinking maybe if you had a power commander on it and the fuel map for that rpm range was just way out of whack that could do it but I also feel that that's such a long shot here

  • Ya 7000 is literally where the 12 is just coming to life

  • Only in second gear may be just dumb luck too. Mine started off happening mostly in 3rd around a particular RPM but as the problem got worse, the RPM range spread and it started appearing in multiple gears.

  • Only got an aftermarket exhaust and bmc air filters that i know if everything els looks standard
