Maybe change injectors then (although I can't see how they would make temp rise)

Less fuel is getting through.
Fuel in a cylinder has a small but critical cooling effect before it ignites.

Not convinced about injectors as you'd feel the bike down on power, and it'd run noticeably badly when cold and the injector pulsewidth is much higher to cope with fuel condensing out in the head.

From what you've said, the overheating problem came on quite quickly. Injectors do not lose flow suddenly, in general.

I'm not unconvinced though.
If it lost power gradually would it be noticeable, and how much would be put down to the whopping mileage?
Spookily enough it has been idling a bit erratically too, and I'm not just saying that.
Triumph dismissed that as OBS. Old Bike Syndrome.

That was my thinking that i would feel the bike down on power, in isolation it felt fine.
However a mate had an 04 (mine was 06) version of the same bike and riding them back to back it was clear mine had issues.

I'm not saying it's going to magically fix this Triumph, but is something to think about.

Partially clogged or sticky injectors are much worse at low injector pulse widths, i.e. hot engine and smaller throttle openings. A weak mixture not only has less cooling effect to start with, but burns more slowly so dumps more heat into the cylinder and head.

However if the injectors were bad enough to cause overheating I'd expect the bike to be pretty horrible to ride with poor throttle response and surging etc.

O/P, I have somewhere amongst the smorgasbord of st in my garage a spare set of injectors from a 1050 Speed Triple, basically the same part iirc...

Pm me your address and I'll stick them in the post, no charge for the injectors just stick the postage cost in the Poppy Appeal tin in a week or two when they start collecting smile

For those who haven't lost the will to live yet....
I have news.

So I'm about half a tank/100 miles in to using some treated fuel - with Archoil 6400 added to it.
It's definitely had some effect, which does seem to point to the injectors being clogged. Whether this is the cause of the cooling issue I just don't know, time will tell, but for now at least, even after the short treatment period, the bike is perceivably smoother, more responsive and generally a bit more zippy than it had become of late.
The cooling?.....I think we may be on to something. It does still get hot, but yesterday going to work it took longer to get to the same high level on the gauge.
Once I've got a bit more free time my intention is to get the spare injectors donated by Tango13 ultrasonically cleaned and then fit them "as new".

Now we're in Autumn I find myself riding on some days that are warmer than some of those back in the "summer".
Yesterday was one of those days.

So it's the end of the road.
New bike being collected on Saturday. I've gone for another Tiger 1050 as it fits my requirements so very well (one reason I was keen to sort the problem but hey ho).
Old bike is getting worse by the mile. Even with the recent colder weather the temperature gauge has regularly got to seven bars and the fan runs soon after getting slowed by busy traffic. On my way to view the new bike I stopped to check directions, and after a completely low-stress ride in sub-zero conditions, in the time it took to stop, de-glove, take out my phone, open Google maps and type in a postcode it'd rocketed to eight bars.
So, got me a 2008 bike in black, with 14k on the clock. Low enough miles to be sound, old enough to be low outlay.
It needs some reverse engineering to remove a few bits of pointless bling, and I'm planning then on swapping all the best bits from my current bike (heated grips, K&N etc).
First to go will be the slightly bodged HID light conversion which I'll replace with the Tiger Sport upgrade I did to the old bike.

True. It was something else I raised with Triumph but in the end, given the ever increasing temperature and in particular the rate at which it's worsening they were pretty doubtful.
I feel I should return them boxedin

What are you doing with the old bike then? I feel like someone should buy it and find out what the hell the problem really is! biggrin

My local indy bike place is having it off me.
It needs new tyres and pads for its MoT which would set me back circa £250.....to make it worth what?.......£750?
So they've given me £500 for it as it stands.

Every used bike needs something, almost always tyres, brakes and a service.

A real shame so many of the suggestions here and donation wasn't tried. Could have saved you £500 or more.

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.
