kymco agility 50 4t tuning without wasting money on random parts

I am starting a kymco agility 50 4t tuning thread because the scooter struggles on one hill. I know 50cc is 50cc, so I want a realistic checklist before parts.
I found this related page while comparing notes: kymco agility 50 4t tuning. I wanted a practical thread before ordering parts.
Would you check belt width, roller shape, variator ramps, clutch dust, air filter, plug, valve clearance, brake drag, tire pressure, battery voltage and the same hill before tuning parts?
