The thermostat is on top of the engine just behind the radiator...beyond the obvious possibilities,eg..bad water pump,plugged radiator(inside or outside),bad or stuck thermostat,etc...
Don't forget about ignition timing and fuel...if the timing is off or the bike is running lean,it can overheat.

Thanks for that I have only jut acquired the trike and someone has over filled the oil which spat its dummy out all over the engine !!! maybe this was part of the cause? the fan is wired to stay on full time !!! so im guessing thermostat is stuck or sticking as i have drained and found NO coolant in the system (how can people be so stupid and living in a hot country too) so maybe this also ...today the bike is stripped oil dropped (all 5 litres of it !!!!!!!) plugs filters changed rad dropped and flushed new filters and one cam cover and the timing belt cover gasket replaced....then i will go from there.... thanks for your help and advice...ill keep posting

took rad cover off and low and behold a big hole in there at the very top of the rad lol too easy but didnt see the water leaking so it must have drained out pretty fast
replacement rad coming no to sort where all the oil spat out compression is spot on so before i start on all the gaskets i need to find where it came from

I just replied to your other post (1977 GL1000 oil leak) and I'm now reading this one. (I suggest you post only one thread about your bike and stick with that one, rather than posting multiple threads. It's less confusing for those who want to help you.

From what you've said so far concerning the condition of this GL, if it were mine, I'd be pulling the engine and doing a complete ground-up restoration. The things that you have encountered so far, indicate that the PO (or PO's) were very careless and what you've found up to this point is only the tip of the iceberg. Trying to salvage a bike that has this many problems with 'one by one' repairs is very difficult. Consider tearing it down so everything can be inspected.
