piaggio x10 125 tuning before blaming the engine

I am looking at piaggio x10 125 tuning because this scooter feels heavy off the line and lazy up a local hill. I think the first job is figuring out what the CVT is doing.
I found this related page while comparing options: piaggio x10 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?
