piaggio fly 125 tuning for cleaner launch without guesswork

I am helping with piaggio fly 125 tuning because the scooter feels lazy off the line and a bit tired on a hill. Before tuning parts, I want to see what the CVT is doing.
I found this related page while comparing options: piaggio fly 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 hill test before parts?

Do not change rollers and spring together.
The CVT already has enough tiny opinions.
That is the right piaggio fly 125 tuning method: measure losses before buying parts.
