piaggio medley 125 tuning for smoother city and ring-road use

I am opening a piaggio medley 125 tuning thread because a friend wants better launch in town and less struggle on the ring road. I suspect CVT service will matter more than flashy parts.
I found this related page while comparing options: piaggio medley 125 tuning. I wanted a practical discussion before ordering anything.
Would you check belt width, roller wear, variator ramps, clutch dust, air filter, plug, brake drag, tire pressure, battery voltage and a repeatable roll-on before tuning parts?

Check brake drag too.
Correct. piaggio medley 125 tuning should be CVT check, drag check, road test, then one change.
One commute tank after baseline.

Do not change rollers and spring together.
The CVT already has enough opinions.
