The daytime running lights are tied to the fuel pump circuit, If you want to remove them there is a small diode near the steering stem left side staring at the bike on the main cable harness, pulling the diode will kill the running light and the lights will fully turn off in the off position. The diode is about 1cm across and 2cm long (black rectangle plugged into white plastic retainer).
For the problem with the thermoswitch, make sure it matches the photo I have attached, this should end your problems for now, There are still a lot of old style thermoswitches out the that are prone to premature failure.
Customer service , sorry I can't help you with that.
