So i just got a zx12r and i test drove it and it seemed good but i couldnt open it up because of city traffic. Got it home, pulled the clutch in while riding, went to rev it, and it revs to 7k and dies. Went back home and investigated. Rpms drop to almost nothing and it revs back up and dies again. It wont go above 7k at any throttle position it only dies and revs up again at near WOT and WOT. The more throttle i give it the more it surges.
