This video shows hands on experience how to fix a Honda engine overheating problem. On 2020 Honda Ruckus scooter the engine overheat lamp turned on after riding a moped at nominal speeds after 5min. This video shows how to resolve this issue by simply removing the thermostat so that the radiator starts to be operational (gets enough coolant flow) and cools the engine properly. The culprit in this case was a faulty thermostat which did not open at the low enough temperature to get the cooling system to work.
