You are correct, without the enricher the bike wont start. I tried giving the bike some throttle before it dies but it did not help. I was assuming this is because then enricher bypasses all the circuits in the carb?Hmmm. I somewhat agree. But he did say that the engine quits "gracefully" at 3k, which leads me to believe that it is an ignition issue, or a massive flooding situation. I was going to suggest connecting a timing light with an inductive pickup, but I assumed that he did not possess one.
I figured that ruling out fuel starvation would take the carbs out of consideration, as I really don't see massive flooding as a probability, if: turning off the enrichener will not allow the bike to start, and then after starting, turning off the enrichener does nothing to improve the situation. I am also assuming that any changes in throttle input or enrichener plunger positions have had no positive effect during the repeated "climb to 3k and die gracefully" scenario.
When the engine does start, it is apparently running on both cylinders, and it is dying immediately after starting and climbing to 3k. Fuel starvation would seem to be the most obvious choice here, but the fact that the engine dies without even a hiccup leads me to believe that it is ignition. If it is ignition, then it is most likely an issue with BOTH coils, which likely means that it is coming from somewhere BEFORE the coil high tension circuit- a voltage drop on the low tension side due to a bad fuse, connection, dead battery cell, or god knows what else. The chance that both coils are fried seems improbable, but not impossible (and a fried coil could behave exactly like this).
I think that voltage reading was taken with the battery tender plugged-in, as 14.5 volts is unlikely with everything static, unless there is something about these new lithium batteries that allows them to sit at 14.4V when they are unplugged. Dead cell would hamper starting, so I'm not thinking it is battery related.
Yes, this could be troubleshot much more quickly, but I'm not the one hearing the bike run or in control of the probes... so we move at a more careful pace and have to be more patient.
You are correct, when the engine dies it does not hiccup or sputter.
The 14.5v I read from the lithium battery was it off the tender.
As for flooding, when I removed the spark plugs I did see some moisture on the vertical one but the horizontal one was exceptionally clean and dry. I dont understand how it could be flooding if before the bike was starting and idling fine. Last week, the bike started with the enricher but would not idle when I closed the enricher. I had to give the bike a little of throttle or else it would die. Not sure if that is some sort of clue.
