It's a little early in the day for me to think this one through but remember that with a single point both plugs fire at the same time. One will go on a compression stroke (and hopefully spark) and the other will go harmlessly on an exhaust stroke.
If you think you don't have spark at the points try this: Put your bike in the shade and take off the cover. Turn the engine over by hand until the points close. Turn on the ignition. Take your finger and separate/open the points. Your should see a spark at the points and also hear a slight "tink" sound as the plugs fire. It helps to make sure your bike is in neutral when you try this.
Alternatively, pull one or both plugs and hook the spark plug cables back up. Turn the ignition on. Hold one plug's curved electrode against the head away from the spark plug hole and have someone kick the bike over. If everything works you will see the plug(s) fire and hear an audible snap. Repeat this with the other plug on the other cylinder.
Again, using a sleepy brain, I suspect you have have a condensor starting to go south. Normally a bad condensor will allow one or both cylinders to fire once or twice and then die. The bike tries its best to start but just can't seem to make it happen. Very old gasoline in a bike that has not been run in a long time will cause the same problem.
However, -----------if the problem is your "one kick" bike is now a "two kick bike," count your blessings. Maybe the choke is slightly more open or closed, or you are holding the throttle more open or closed, etc., without realizing it. A "one kick" bike "becoming a "two kick" bike isn't much of a problem.
