KT35D Thermo-Bob Kit

Description

This kit is for 2019-2022 KTM350 SX-F and XC-F, 2019-2022 Husqvarna FC and FX350, and the 2019-2022 GasGas EX350.  There is no factory thermostatic control on those bikes, so coolant temps can vary widely.

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.

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.
