Avoiding a "Push" start
I grew up with carbs, a real choke and the introduction of electronic ignition and ABS. And one other feature I miss today, the kick-start. Thought it would remain a "classic bike essential", but probably for many good reasons is now relegated to history.
Anyway, I continue to learn more after a couple of years of ownership of my 2013 Thruxton, much of it from this forum.
Problem: I have found during the last two years an intermittent failure of the engine to turn when pushing the start button. No apparent reason....just nothing, no click, no struggling to turn, nothing. In the past I have been able to jump start, either on a slope, or with the aid of a bystander pushing until I get the speed up to nudge it into second gear and release the clutch. This happens intermittently with both cold and warm starts, always with the choke leaver "in". I normally find the choke button is not needed in warm weather, and usually the engine will spin just fine at first touch of the button.
Solution: I recently read somewhere on this forum a less strenuous solution that hasn't failed me yet...thought I'd reiterate. If the engine is silent after attempting to start, pull the choke to the first stop (even when warm) and press start again. For some reason the engine will spin and burst into life immediately. (Don't forget to push it all the way in after you are started).
My experience has been 100% success on this. So can anyone tell me what magic is working here? Obviously it's an EFI bike. Is the ECM bypassing or overriding something to provide the juice/power when I pull the choke out? I had assumed the battery was at fault, but if it starts with the choke out I'll assume the battery is fine?
Thoughts anyone? Just curious!
