Problem starting when hot..... Is the starter motor the problem?

[Gasman]

Bought mine from World of Triumph £340 posted received the next day. Priced it at my local dealers to see if I’d been ripped off and they quoted £480.

Dealer high quote is likely the fitted price as Triumph dealer parts prices should be the same at any dealer based on the official Triumph network parts catalogue. Both World of Triumph and Fowlers parts lists (depending on exact model) show the starter in the £323 - £332 bracket.

I had the same problem and it is cured for free  .. Apparently, you slightly twist the throttle when pressing the start/ignition button. It is more of a habit, if you had motorbikes with carburettors in the past.
The fuel injector is controlled by computerised engine-management system, which read the engine temperature and the ambient air temperature, and then determine how much fuel and air to send into the cylinder when you start the bike.
In some cases the engine stalls or start more slowly when the bike is hot. That's because you opening the throttle slightly when the computer wants it closed. As a result, the cylinder gets flooded with petrol.
I was able to reproduce the 'problem' numerous times, in order to make sure there is no problem with the bike.
I was told the above from the Triumph Dealer in Cardiff UK and I also made a research myself. Apparently the fuel injected cars have the same habit. 

Hope this is helpful.

Can you please confirm that "you slightly twist the throttle when pressing the start/ignition button" is an erroneous habit that is done inadvertently thus causing the no start problem?

Sorry but I read your statement both ways - Observation and Instruction!!!

Hi there,

Apologies for my writing. I confirm that twisting the throttle (even few millimetres) is an erroneous habit that is done inadvertently, thus causing the no start problem.
In order to remember it, I take off my hand completely from the throttle when starting the bike (even if it's cold).
I hope this would fix your problem.
It worth noting though, that in colder climates (I had the bike in Scotland for 2 years) I never encountered this 'problem'. First time I faced it was during a trip in Greece with 35 degrees Celsius.
Anyhow, the manufacturer suggest that we shouldn't twist the throttle when starting the bike.

has anyone in the uk got a starter they don't want with the brush/ring/heat prob? I have a few well educated mates in the starter/genny/ecu industry into this sort of thing,
if they can see one and can pinpoint the problem(s) they maybe could come up with an easier/cheaper, permanent fix for it, or even figure out what else (better/stronger) fits..

pm me if you have such a thing

You don't actually need to be an expert. The starter motor brushes wear and once they wear they don't generate power as they rotate. Better brushes is all that Triumph need to install to solve the issue.

Been doing some reading about this topic as my 2011 Tiger has these exact symptoms (doesn’t want to start when it’s running hot. Usually when the fan is running). I have a bit over 30,000 miles. Wondering wheat the miles on the bike were for others with this issue. I’m looking to get one of those starters from Rick’s Motorsports to replace the OEM one. But it’s funny, neither Triumph Shop in Oregon has ever heard of this starter issue.  Wondering if I should also contact Triumph to at least let them know what’s going on even though I’m far from being in warranty.

(2013 xc) Mine started at about 50k miles and I replaced it at 54k miles with a triumph part.

I believe that triumph know very well that there is an issue (hence the replacement part is a different part number) but will not admit it publicly.

Interesting....  thanks for letting me know. And I think I’m gonna contact Triumph anyways, if nothing else then to give them a bit of sh*t for being cheap on the brushes.
