Last year on very hot days, in traffic, with the fan switched on manually I was overheating.
Once out of the traffic and on open roads no problem.
Took my thermostat out today and dunked it in a jar of boiling water and it opened, so that seems Ok.
Put it all back together and ran engine almost to red on gauge and Fan did not cut in ( I purposely didn't switch it on Manually so as to see if it worked automatically) The bike blew water out of the little expansion tank, then I stopped the engine and could hear the water boiling. I have a spare thermostatic Rad switch witch I will try tomorrow.
Thinking about a new thermostat, but don't want to spend unnecessary money.
My questions are: where on the temp gauge is the fan supposed to cut in?
How far should the thermostat open?
Shall I take thermostat out altogether?
Would appreciate comments, thanks.
