Why haven't you had your PCM flashed for your 750s?
Adjusting A/F with fuel pressure when you have a DSP is ridiculous.
Your spark is "blowing out" aka misfiring, because their fouled from running too rich.

Get a CMR to rescaled your PCM for the 750cc, set the fuel pressure at 58psi and you'll have stock drivability.
