Quicker acceleration ET4 150 cc

Hi, can anyone give me tips on gaining quicker acceleration and better throttle response. I have been told that Lighter Variator weights and different clutch spring will provide quicker acceleration, if so can anyone please give me advice on a good combination 

I'm new to the automatic clutch scooter and I am just trying to get advice on improving acclamation on my Wife's ET. SIP will not give me advice and said I should use this forum, the above is the second post I have put up in 8 weeks and I have not have had 1 reply. Is this not what the forum is for? If not SIP please give me advice as I will be buying the parts from you
