    Re pitch that prop to 14/19 and it will be up near 7400 with better throttle response.

    Also check your pump venturi nozzle opening size. 98 & 99 XP-L's came with a 84.5mm/3.327" nozzle. The 98 GSX-L (271 000 875) came with a 87mm/3.425” nozzle. You could try this larger nozzle with your existing prop to see if it gets you to where you want to be RPM wise.

    I think you are doing vey well. I have a 2001 RX 951 With RXX pipes, Rossier head and had to prop to a 17/22 solas to keep it under the 7185 rev limiter. I have not sent the mpem off yet to reprogram but I gps at 70.4
