I think you are saying, the bike doesn't have power until 7000 rpm under load.
That without a load (neutral) that it revs up fine. That 3-6000 rpm is a dead spot
in the power-band. You are using a K&N air filter and running .128 main jets.

If all of that is correct, check for vacume and/or exhaust leaks. Also, try Seafoam
in the gas tank. Clean and synchronize the carberators if you haven't already.

Good luck, Ern
