Re: [ST] Cranky start

[Markus Clarijs <daftspeed@xxxxxxxxxxx>]

A bit of a late replay due to my second trip this
months (after the "Tour the France" with Emile and
Kees, I went to Devon and Cornwall)

Emile is right, My ST does need a bit longer time
after a hot ride to start again.
This does only occur on longer rides and when the oil
is really hot.

My guess is that this is because de ECU makes the bike
very lean burning. Fueleconomy of 4 to 5 liters per
100km is usual to me. Even while canyon carving of
Autobahn blasting it will never drop below 6
liters/100km.

The ECU is meassuring several variabels such as
throttle-opening, airtemperature, oiltemperature. When
hot, the ECU need some time to recalculate and go over
to a less leaner mode, causing the engine to crank
longer then axpected.

It is not a problem, because it will allways start
again, only seems a bit awkward. It could be resolved
but at a lower fueleconomy, so no thanks!!!
IMO the engine is really anchor spreadable.

Cheers!

Common knowledge perhaps for full time
listers, but I was pleasantly surprised to
find out that the long crank before every
start on every Sprint ST (also the new
models apparently and actually on every
Triumph?) is a feature, not a flaw. My
R1150GS had a long crank before a cold
start, but that was because of the high
compression and sucky battery / starting
system (in my opinion and experience at 
least). It started right away when warmed
up though, but not the Sprint.

To get to the point, I read in a Dutch
review the new Sprint ST also has this
long crank that gives the rider the
impression that either the battery is
almost empty or something is not working
properly. When they gave the feedback
to the guy of Triumph Benelux (which they
do after every test in a little interview)
he said this is because of the manner in
which the injectionsystem determines the
ignition sequence; the crankshaft has to
turn for a short while first because the
pickup sensor works together with the air-
intake pressure-sensor for the sequential
ingiting and injecting. I don't know exactly
what that means, but it sounds cool :-).

Well, that was all... sorry for interupting
the weekend... move along now...
