Get the nugget out Speedy - those brown spots will be gone in no time.

My fan has come on several times during the winter

Happened when letting her run in the garage for 30+ minutes at about 5° ambient. Screw in temp gauge showed about 100°. Since fan is supposed to kick in at 120°, there is a difference of 20°.

Without a fan I would pay attention to the temp gauge. If it hits 100°, turn engine off.

I have had my bike for over 7 years now and in that time the fan has come on twice, both times commuting across london on a hot day.
On a long run my bike doesn't really get above 100

I have had my fan on only in dyno, never in real riding. Maximum oil temp I have seen on the road is 90°C
