I was also wondering if the machine is boiling coolant? I think you can also get an overheat light for oil temperature, and things like a slipping transmission could cause high oil temperature.
Also, what have you got for coolant? Most motorcycle coolant comes premixed 50/50, where many automotive coolants should be mixed 50/50 with distilled water. Ethylene glycol doesn’t carry heat as well as water (but prevents freezing, raises boiling point, and reduces corrosion). Mixing stronger than 50/50 can cause overheating.
