Speed/rev limiter

[73scoutII]

alright time to remove the thrill killer. I ride a 05 roketa rts 250WW. Iv swapped the stock Pz30 with a mikuni 30mm with bigger slow an mains and have a 44 mm airfilter as oppose to the 42mm stock size filter. Yet the rev/ speed (not sure which) will allow faster acceleration and throttle response due to the upgrades but the limiter still wont let me pull more speed or peg out higher rs. So how do I remove the limiter? All I want is a little more speed
