Why is my Triumph getting so bloody hot?

Had a call from a mate last week, he was reporting the same symptoms from his car so I borrowed a sniff tester and gave it a go.
After half an hour ticking over the engine was good and warm but no indication of any combustion gases in the fluid, no overheating, loss of coolant or anything to suggest HGF.
Decided to give it a few more revs and immediately the fluid changed colour and soon after, the coolant started boiling out.
I reckon we could have left it all day on tickover without the fluid changing colour but as soon as the cylinder pressures were increased it was obviously HGF.
Sorry to keep on at this but did the workshop do the sniff test thoroughly?
The most logical reason is usually the right one.After half an hour ticking over the engine was good and warm but no indication of any combustion gases in the fluid, no overheating, loss of coolant or anything to suggest HGF.

And so it appears

Huh? What suggestions are those? I'd replaced pretty much the entire cooling system, flushed it through three times and cleaned the injectors. Not sure what more there was to do.
Anyhow, in salvaging the best bits before it goes, I took the airbox off (to retrieve the K&N) and all the engine breathers were full of mayo and a mix of oil, coolant and gunk had somehow found its way up in to the airbox.
It's fked.
Ok, so at least we know now. Anyhow, in salvaging the best bits before it goes, I took the airbox off (to retrieve the K&N) and all the engine breathers were full of mayo and a mix of oil, coolant and gunk had somehow found its way up in to the airbox.

I have read the whole of this discussion with great interest.
I have a 2017 Sprint ST and it regularly overheats to the point of 10 bars and a flashing red light when in even moderate traffic.
Once out on the open road again it quickly cools back down to 5/6 bars.
It doesn't appear to be losing fluid and the oil is up to the mark.
I've taken off the radiator, flushed both rad and engine every which way, renewed the coolant fluid, and changed the radiator cap. I've had the bike from new and it's only done 26,000 miles and always been serviced annually by Triumph. I'm not just about to get them to diagnose it as all they do is replace components one by one.
Anybody got any new ideas?
Does anyone know whether it could make a difference using high octane fuel as against ordinary regular?
