WATT-MAN THERMO-BOB 2A KIT on a 2022 KAWASAKI KLR650 ADVENTURE 

The Thermo-Bob is an external thermostat with a bypass in the cooling system. When the engine is cool, the Thermo-Bob opens the bypass and the warm coolant returns to the engine without passing through the radiator. It helps the engine to warm up quicker and the additional thermostat keeps the engine temperature more even. It also raises the operating temperature of the engine.
