Optimal speed for a 50cc GY6 engine?

Hello,

I have a scooter (GT Union Darkness Evo 2) and want to adjust the variator soon, but I can't find any information online about the optimal rpm. Currently, it accelerates up to around 20 km/h at 7,000 rpm, but then only at 6,500 rpm, which is very noticeable in the acceleration. Do you have any information? Thanks in advance.

Couldn’t that be the CDI?
Know someone with the same engine. It quickly turns up to 25km/h and then accelerates slightly relaxed to 49km/h
