swm sm 500 r derestrict checks before making it loud and hot

A rider asked about swm sm 500 r derestrict after buying a used supermoto with unknown exhaust and intake work. I want to avoid lean running and legal problems.
I found this related page while comparing notes: swm sm 500 r derestrict. I wanted a practical thread before guessing.
Would you check current map, exhaust baffle, intake setup, air filter, plug color, valve clearance, coolant temp, gearing, clutch, brake drag, ECU codes, fuel range and road legality first?

Discussion

For swm sm 500 r derestrict, log fuel use, speed, voltage or the exact error before changing anything.
Know the current setup before derestricting
Thomas Spagnoli here. swm sm 500 r derestrict should start with a baseline and a bit of humility. The expensive mistake is changing parts before you know what the machine is actually doing.
For swm sm 500 r derestrict, check current map, exhaust baffle, intake setup, air filter, plug color, valve clearance, coolant temp, gearing, clutch, brake drag, ECU codes, fuel range and road legality first.
Good swm sm 500 r derestrict advice should protect the engine from lean heat and keep the bike legal enough for where it is ridden.
