Description
The KX450F is a popular choice as a snow bike, and in those applications, the lack of factory cooling system control leads to cold coolant temps. The carbureted 06-08 bikes then have inconsistent jetting, and the 09-15 EFI bikes end out overfueling, thinking the bike is constantly in ‘warm-up’ mode. The Thermo-Bob 3 is a machined aluminum housing with a 180°F (82°C) thermostat inside, and modifies your cooling system to operate like automotive systems have for decades… keeping coolant flowing all the time through the engine, but not through the radiators until it is up to a selected temperature.
There is also a threaded port in the Thermo-Bob 3 that will accept aftermarket temperature gauges such as the KOSO or TRAIL TECH 1/8-28 BSPP temperature sending units.
