zontes 125 scrambler improve performance with service and GPS baseline

zontes 125 scrambler improve performance forum question

I am helping a rider with zontes 125 scrambler improve performance ideas, but the bike is still stock, has unknown service history and no real GPS baseline. Classic before-photo missing situation.

I found this related page while comparing notes: zontes 125 scrambler improve performance. I wanted a practical thread before ordering parts.

Would you check chain slack, sprockets, tire pressure, brake drag, air filter, valve clearance, plug color, fault codes, GPS both ways and legal limits before buying parts?
