Since the last two weeks while I was trying to start my V on a cold days (2° C, 35° F), I noticed that it took more time to start than what it usually does: Normally I press the start button for half of a second and the bike starts running, but this time I kept the starter button pushed for like 3 or 4 seconds until it finally started. It have been happening since when the bike is cold.
I have seen in other posts that among all the possible reasons, my issue could be explained to either a low battery (due to cold), or a different fuel quality, or a combination of those. Even the cold itself could be the reason, as I will try to explain you shortly.
I noticed that under the circumstances, if I open the throttle just a bit while I press the starter button the bike starts immediately. I further noticed that my issue occurs because when I hit the starter button, the subthrottle valve actuator fully opens the (subthrottle) valve and then slowly begins to close the valve to a semi-closed position, moment in which the engine starts. On the contrary, when the subthrottle valve stays in the semi-closed position at the end of the ignition sequence (as in the video I attach) the bike starts immediately.
FYI, when I start my bike I normally turn on the ignition, I wait until the fuel pump finishes its job (time in which the subthrottle actuator makes its distinctive three whirring noises) and finally I press the starter button.
My questions are thus the following:
What is the boot sequence of the subthrottle actuator when the starter button is pressed?
(It seems that the pressing of the starter button leads to a starting sequence in the throttle body)
If the previous question is positive, does this sequence depends on the outside temperature?
The video I attach was taken today when the outside temperature was approximately (7° C, 45° F) and the subthrottle valve stayed on the semi-open position.
Even worse, does my bike has any problem?
(My bike is a 2007 Versys. I have heard about a glitch in the fuel mapping on the 2007 models, but I don't think it is related to it)
I have searched for starter button sequence on the internet, but I haven't been able to find anything.
I would appreciate very much your interesting contributions. :feedback:
