Hi,

I have a 2004 Buell xb12s.
Since I have this bike I've never heard the cooling fan.
Today it was very warm for this country (the Netherlands), +30 ℃ (= 86 ℉).
I've ridden the bike for half an hour and still didn't hear the fan blowing.
The bike was very hot. Even after half an hour of cooling down I still couldn't even touch the frame/ gas tank.
What is the first thing to check to fix this fan problem?
