My FYK100 has been reliable for the 4 years I've had her, but recently the radiator fan has stayed on when parked after a ride, not turning off till disconnected.
The PO had installed a rheostat, temp probe and manual on/off switch, that now is important in the troubleshooting process.
I have Tom Coradeschi's excellent cooling system troubleshooting guide, and would remove this mod first unless someone has knowledge of it.
Has anyone seen such a mod to a brick K bike?
Thanks in advance for any help.
