Kit includes: External thermostat (and one extra), thermostat housing, bypass hose & fitting, and clamps.
The Watt-Man Thermo-Bob 2 is a cooling system modification for the KLR 650 from 1987 - 2017.
In stock form, the KLR runs too cool when ridden in temps below about 80F.
The colder outside, the worse a stock bike is. Plus, the factory cooling system relies on surges of cold coolant every 30 seconds at the bottom of the cylinder to control engine temperature.
The Thermo-Bob 2 eliminates the inconsistent engine temperature on the stock KLR650 and keeps it running at an optimal 195 degrees for better performance and longer engine life.
Easy installation and made in the USA.
The Thermo-Bob is a machined, hard-anodized aluminum external thermostat with a coolant bypass. It allows coolant to bypass the radiator during warm-up, speeding warm-up and eliminating the surges of cold coolant year-round. It also raises the operating temperature at the top of the cylinder to 195°F from 160°F more importantly, it raises the operating temperature at the bottom of the cylinder to 185°F from downright cold, (ie as cold as 30°F). It should eliminate the out-of-round cylinders that are common to the KLR as it ages which usually results in increased oil consumption. The warmer temps should extend engine life as well as increase oil change intervals, and improve economy by a few MPG.
