Thermo-Bob 4 Snow Bike Thermostat - Husqvarna/KTM 250/350

When these bikes are used as a snow bike, the lack of factory cooling system control leads to cold coolant temps.  The EFI sees cold coolant and overfuels, thinking the bike is constantly in 'warm-up' mode.  The Thermo-Bob 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. 

This kit also includes two L-bend hoses to complete the installation.
