@Conspiers many thanks for the info, it's indeed the starter motor, when hot and unable to crank, I just took a piece of wood or rubber mallet and hit it hard, it runs beautifully now.

Well the guy bought a new starter motor and fitted it and problem was still there.
So he took it back and got his money back.
It's a voltage issue but cannot define if its stator or reg/rectifier.
No one seams to be able to give the limit specs for reg/rectifier.
Triumph customer care are next to useless and I personally wouldn't buy one
I like my jap bikes too much
Here's hoping I can resolve the issue.

Here is a tip, any time you go to replace a starter motor, make sure the starter clutch is working properly. Stick your finger in the hole and the gear should turn free and smooth one way but not the other. If the gear does not turn then your starter clutch is shot and it will just ruin the new starter.

Another important info, thank you, I love this forum.

I did also replace my Voltage Regulator and Stator prior to the starter, probably unnecessarily, but maybe multiple components had issues. I will say that my voltage regulator was all ready replaced once prior under recall and it is a known problem for these bikes. If it hasn't been done on the bike you are working on it would be high on my list. Also a pretty easy job and I picked up the part online easily.

Awesome, I'm glad to be of help after the hours and months of frustration I went through. Unfortunately SpeedTriple675 is still battling the machine.

After going through a tank of gas since my starter was replaced, my bike failed to start after I made a quick stop home today. It wouldn't crank at all. I swapped the battery and it fired right up. (Sigh) back to the shop next chance I get.

Stator doesn't charge the battery?

When holding the RPM up into the range (2500? I forget the number in the repair guide), the voltage does climb, appearing that the stator is charging at that RPM. The shop that has the bike said they did analysis and did not expect the stator, at least not so far. As far as what happens in between revving the bike at a stand still and what happens during a 30 minute ride, I couldn't say. Which is my next puzzle piece: I think it's worse than "Not charging", it drains the battery. I can go out with a fully charged battery and in ~15 minutes, turn off bike, key on, the bike is unable to start. This was attributed to bad starter when hot theory, but now I've got a new starter and a dead battery. Would a 'non charging' stator cause the battery to deplete that fast?

Get a cheap voltage meter, and connect it to the battery terminal, check it during the ride. It will tell you a lot.
