Scooterotica

hi all
hope someone can help i am running a polini 210 alloy kit with standard si 24 carb,57mm crank fast flow tap have changed main jet to a 132 ,seems to run ok,apart from after being full throttle and then shutting off then trying to open throttle there is a deadspot for a couple of secs,also seems to be spluttering when riding at 1/4 throttle was thinking possible jetting issue

thanks in advance
