California residents: WARNING


A thermostat kit is essential for helping your snow bike’s engine run at normal operating temperatures and prevent EFI overfueling. 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 thermostat 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.
