increase power 125 zones and what to check before chasing derestriction

The owner wrote increase power 125 zones, and I am pretty sure they mean a Zontes 125. Either way, it is a 125 street bike and I want to avoid fake horsepower talk.
I found this related page while comparing notes: increase power 125 zones. I wanted a practical thread before ordering parts.
Would you check exact model, legal limits, GPS speed, chain drag, sprocket ratio, valve clearance, clutch slip, plug color, intake leaks, exhaust leaks and fuel range first?
