Hi Paul

Most of what you quote was speculation/question, not fact.

I am one of about three listers who have a 'fast idle' problem.  Mine
is still with me because I haven't done a lot about it.

The bike is fantastic to ride and maintain, looks good too.

Gents,

I've just joined the group - mainly to eaves drop to find out more
about the
Triumph (ST) before I decide to buy. From what you are all saying is
this
bike worth purchasing given all the issues that you are raising??? What
with
faulty ECU's, dirty switches, missing engines (not literally!) I'm
becoming
a little sceptical......

Regards,

Paul

David,
    I have had this sort of thing happen twice in 60K miles on my 2000

ST. Once it happened at a gas station as I had stopped to fill my tank

and for some reason I had to move to another pump, so I started the
bike 
  and immediately dropped it into gear and then stalled it. After 
filling up the bike would not idle. I rode it several miles stopping at

lights with it dieing. Took it out on a freeway and ran in several
miles 
and then pulled over. It died and after about 3 minutes I restarted it

and it ran fine. I attribute this to the throttle body sensor getting 
out of step with the ECU and it taking some time for the ECU to 
recalculate its position. The second time it happened, an new problem 
had developed in that it would idle at 1200 rpm with the clutch in at a

light, but would jump to 1800-2000 rpm it it shifted into neutral. The

bike died on me as I was coasting to a stop at an inspection station a

couple of times. I took it to the Dealer and had the O2 checked and
set. 
Never found out of it was out of spec, and also had the sport bike tune

checked. I have a Power Max exhaust on it. After coming back from the 
dealers the idle problem is still there but it has not died at anytime

since unless I shut it off. I alway use the ignition key to stop it and

never the kill switch. I have heard that using the kill switch does not

give the ECU enough time to make note of the current throttle body 
position and to take other readings before it stops.

I checked all the FI related wiring and all seems well.  I have two
new
things to check, the fuses, to make sure there's no intermittant crap
in
their, and the ECU.  Like you state, it looks like an ECU issue.  The
battery was out for two weeks while I performed the service and fixed
some
little problems, so maybe it needs to be reset.  I'll look into that.
Like you, I always use the key to shut down, never the killl switch.

Is there not a user-servicable ECU reset proceedure?  I know the
engine
light will stay on for three start cycles.  btw, my check engine light
never
comes on, until the bike dies.  

I rode it about 25 miles today, and some clarity and another issue
emerged.
Twice, right before the engine died, so did the tach.  Once idling in
my
garage just after I got it buttoned back up from checking all the fuel
tank
wiring, and then on my way to work the tach quit and it immediately
died
when I let off the throttle.  (It ran fine for about a 1/4 mile without
the
tach)
It also seems to happen nearly always at idle. Yesterday it stumbled
twice
under power, today once.  But it rarely will idle more than a minute
without
stalling.

I had a bit of an issue with my '06 at about 2,000 miles where the
kick
stand switch went a little iffy on me. It was pretty obviously the
problem because the engine would quit on one especially rough patch of
roadway that I cross almost every time I ride. I pulled the switch
off,
cleaned everything in the area, and re-installed it and the problem
hasn't been back. 



I gave that a good check today.  All seems well.  Once again, it
rarely
happens underway, always at idle.  It seemed to have quit after I
sprayed
the switch with contact cleaner, but it came back as soon as I started
riding.

Thanks,

David
