cooling fan

I have been out on my scooter for most of the day, temp has been about 17 degrees c,
When I stop I notice the fan is running, is this unusual, I have been for a run for about 25 miles, and not caught in traffic, surely the fan should not be on as the engine is getting enough air cooling, this makes me think the fan is on all the time, this cannot be normal can it ?

Since the gauge shows no more than three digits, you're OK.Try though to clean the radiator with mild water pressure from the outside.

If the gauge shows only three bars you should be ok. The S/W is really not known for overheating. I have noticed my S/W coolant fan will run more at higher altitudes (12k-14k feet) like Pikes Peak.  Howard

Bikerboy1000 if the fan runs all the time your thermostat could be bad. If the fan cycles on and off and you're not showing hot on the gage your scooter is running normal.

If the fan runs all the time it's more likely the thermostatic fan switch is not opening. If that's the case the fan should run even when you first start the engine in the morning. If the switch is bad you'd have the fan running with the temp gauge showing normal or lower temperature. Low coolant or a scaled radiator could also cause the engine to run overly hot but that will show on the gauge as a hot engine.
To do any trouble shooting you need to find out when the fan comes on. They are usually loud enough to hear when they come on. Get a check of what your temp gauge reads (number of blocks) when the fan is on and when it's off if it isn't running all the time. The gauge should be well above half way when the fan starts on. Let us know what you turn up.

When I drive around in 90 degree weather and shut the engine down and turn the key to on the fan will run even with only three bars showing. The fan runs for a few minutes and turn off. When the engine is shut down it gets pretty hot in the engine compartment because there is no air flowing through radiator. My car and truck will turn on fan also after stopping but water temp gauge is in normal range. So I'm not overly concern with Silverwing's fan.

Good idea but make sure you do it from the backside of the radiator. With the radiator cool I use a good mix of Dawn dish washing soap and water and soak the fins at least overnight then flush, it may surprise you what comes out of those fins.
