I have been driving mine now for 2 years and have never had the fan come on. Temps last summer in the 90's but the bike was cool as a cucumber. I do change all fluids every year and as matter of fact just did it today and I am ready to go.

The thermostat opens and closes to keep the coolant within operating range. The thermostat starts opening at 136-144F (58-62C) and is fully open at about 167F (75C).[/size]The fan doesn't come on until the coolant reaches between 212 and 230F(100-110C) and it will go off again at between 207-217(97-103C).

Drifters tend to run "cool" except on the hottest days, stop and go traffic, etc. If you aren't getting indications of overheating, just keep your eyes and ears open. Sometimes it only runs for a few seconds, and that's enough to get it cooled down. You've probably just missed it.

Hi, it came to me today, that I have never heard the cooling fan on my 1500 kick in before; I took an '08 Classic out for a ride in cool weather, it kicked in and out regularly; has anyone else run into this, the fan never running? My temp light never comes on, so not sure if there is a problem or not. This is my first water cooled bike, so not all that familiar with it.

Thanks in advance;
