500R: Cold engine dies at a quick stop

[evolver]

Let's say it is around 85 degrees outside. I start the engine and pull my gloves and helmet on. In about 1 minute after starting the engine I start moving (the choke is still on but not all the way). If in this situation I come to a quick stop from about 20 mph, the engine dies. I definitely pull the clutch lever and not just grab the front brake but rather squeeze it to achieve the desired stopping power.

I do not see any reason for the engine to die in this case? Well, I might think that it has something to do with the fuel level in the carb and the fact that the choke is not off yet but I do not know if it is realistic... When the engine is warm and the choke is released, braking does not affect the running engine.

So, what can it be? Any ideas?

mine did something like that, only it was around 20 degrees. how long has it been since you've cleaned your air filter? that's what the problem on mine was.

if not that, then i dunno, other than it might not like the choke being on that long.

You should never ride with the choke on, it will make your bike run super rich and foul spark plugs. Its also possible that its draining the bowls in your carbs and you don't have the vaccum to pull enough gas to fill them back up at idle.
