Thank you all for the input.
Here is what happened so far:
I fetched my SuperTenere on Friday afternoon.
I was a bit early and scored a cup of coffee with real milk from the owner/dealer.
The setting is now 15 and the front ABS system has been replaced.
Wayne, the workshop manager, was parking the bike and felt the ABS kick in where it shouldn't have. So I wasn't imagining it.
Wayne was very professional about everything this time. The mechanic, Lyle and he went all out to explain to me what has been done and how they tested things.
Wayne and Lyle had me stand on the bike without the seat and hold the brakes, hand and foot, while they ran the diagnostics, and both levers pushed out. This was to show me that the brakes are in order.
They showed me how to access the settings via my dash, should the settings of 15 not work. This is a relief as it is easy to do yourself. You do it for each cylinder. I now feel more confident.
Danny is trying out the setting on his bike, according to Wayne, and says Danny can feel a difference in performance. So that seems to be the right direction.
I now need a few hot days, and a few weeks, to see if the pop/stall is a thing of the past. If not, I'll try -15, as that was the original recommendation on the Wilddog forum, now that I can do this myself. I ended up settling on +15 as the setting of +10 had softened the pop, although the bike felt weak. At +15 the Ten feels fine.
I have not gone out to put down a line yet, as I had a pillion. The STen hasn't had the adverse reaction of the brakes, going up my driveway, though.
Of course, now my bike is heavy on juice,
as I go everywhere at full tilt. I hope I even out soon.
(Enjoying the extra horses.)
My daughter was pillion on Sunday for a short test, and says I'm a show-off.
So far so good, but only time will tell, as I learned previously.
I have a more positive outlook on the matter now.
I also feel I have been heard, and that should I not be happy and cannot sort the stalling, I have somewhere I can call for a different approach.
