allo steve,i had a 750r for 4 years and they do take some looking after .but the rewards are well worth it.check that your exup cable hasn't snapped or seized,or that the exup valve isn't seized.it sounds like the valve is not opening. hope this helps.

sounds like crap in the carbs bro my thou exup's done it a few times when the fuel level got low or the other thing i've had is moisture in the fuel / carbs if the bikes been kept outside / left standing in the damp for a period ov time...add a wee bit ov redex to the tank and take it for a run that should help.

are you running an in-line fuel filter?, that may help prevent it sucking shite from the bottom of your tank in future, get some fuel treatment and give it a good blast to clear it out a bit, if it still doesnt get better you may need to strip down the carb and clean out any obstructions, blocked jets e.t.c

have you tried it on fresh fuel?, contaminated fuel can give a bike some dodgey symptoms
