Engine stops after a few seconds
Dear all,
I first would like to thank all for your time and advice.
I have a 2001 Fatboy and every time I start the bike it turns off immediately after a few seconds, I'm quite good at rebuilding carbs and have meticulously rebuild this 3 times so far taking care to get everything right, but it seems the problem is elsewhere, please look at the video attached and advice me as to what you believe could be the problem.
I thank you all in advance.
Reza.

How many miles? After it stalls, it runs fine?
Why are you leaving your hand by enricher? its ok to leave it on for a while. Are you turning it off as soon as it start? is this bike new to you?

Hello and thank you all for the replies.
Regarding this, since it's a carb bike I don't think there is any EFI on this, and I bypassed any fuel filters and petcocks for this testing phase.

But did you rebuild the carbs three times, because you had the bike so long, or for the same problem? If for the same problem what made you initially rebuild it? I am all for parodically replacing diaphragm and cleaning, just want to know why you did it.

for some reason the file downloads but cannot play it.
what ignition?
some ignitions have over current protection and will shut down if the fault occurs. put some inline spark testers on the wire and see if the ignition drops out.
kiss it first, aka, wiring and connections. then if you have the fsm, troubleshoot the the system.
if you have the crank sensor, check its output. check for debris on the tip. you can have a signal but it must have enough amplitude to carry the ignition, use a peak voltage test.

It might be something wrong with the ignition module but you should get an engine light..
