Are there any other symptoms? Does the bike run fine up until that rpm? What mods are done to the bike?

No self programmable rev limiter unless you have an ignition module or something.

Sounds like the fuel pump issue that is common around here. You can check it out but you'll need a manual to get the specs. www.helminc.com sells the factory service manual. like $60

Well, It has to be air or fuel causing the problem. Check the air filter and change if needed. If that's clean and you see the throttle bodies open when you turn the throttle, then you have the air part checked.

Next is fuel. If you have the right fuel pressure and enough fuel flow from the pump ( which is the thing I said earlier to check) Then a clogged or pinched fuel line will cause your problem then that leaves the fuel injectors.

Maybe some fuel injector cleaner or take them out and have them cleaned.

Then the last thing if all else is good would be the ECU not telling the fuel injectors how much fuel to give. It gets that amount from the Throttle Position Sensor and the Tach. The Manual talkes about the readings you should be getting from the TPS.

If all that checks out, I don't know what else to look at.

You missed the ever popular pinched vent hose is about all dcope - the one other possibility to D's list is the vent hose for the tank is pinched just enough that when the pump gets to the fuel demand level required for north of 12k rpm, it not allowing enough air in to displace the fuel being sucked out....
