Description

 

This kit is for 2011 thru 2015 KTM250/350 SX-F and XC-F, and also fits the 2014-2015 Husqvarna FC/FX350.  There is no factory thermostatic control, so coolant tem can vary widely.

When these bikes are used in the snow, 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 a U-bend hose to complete the installation.

There is also a threaded port in the Thermo-Bob 4 that will accept aftermarket temperature gauges such as the KOSO or TRAIL TECH 1/8-28 BSPP temperature sending units.
