Question about Motorcycles
Razor electric scooter e 300 battery charges but won't run
First check to ensure the batter has held the charge you put into it. Just plugging the charger in does not mean the battery is holding the charge. If the battery is bad, it will drain as fast as you put it in. if the batter holds a charge, should be able to disconnect the charger and battery will show charge. if so, you have a bad connection or motor.

The spark must occur at the right time. Just about all scooters made since around 1980 have an electronic ignition. These systems can rarely be set. In general, the spark occurs just before the piston reaches the top of it's stroke. There is a slight delay between the spark plug fire and the fuel-air mixture ignition. That's why the spark occurs a little early. Most ignition systems have an advance unit build in. As the engine speeds up, the time of the spark retards a little bit. This helps the engine fire the mixture at the proper time
There are a lot of tiny fuel and air passageways in the carburetor that must be kept clean it order for your scooter to run right. Carefully, take the carburetor apart. This can be relative easy (on a 50cc scooter). The carb has tiny passages that can get gummed up. Your scooter will not run correctly if the carburetor isn't completely clean, so take your time. I use a gallon container of carb dip (you can get a gallon at your local auto supply store).
First, remove all of the rubber and gaskets or they will get damaged. After a 20 minute soaking in carb dip, I blow out the carb with compressed air. You have to get all the jets and the passageways clean. Be sure the jets are clear, especially the starter jet. Sometimes carb cleaner won't clear out these tiny jets. Use a guitar or a piano string, a strand of copper electrical wire, or a tiny drill bit pin vise. Be sure not to increase the size of the hole in the starter jet or you'll change the tuning. Carefully reassemble everything, checking for cracks in the rubber carb boots and the gaskets. Replace them if they are old and cracked. Be sure and remove all rubber and gasket material first or they could get ruined. Spray carb cleaner also works if you're diligent.
If you have an electric choke, check it to make sure it works. Check the resistance between the wires - you should see around 10 ohms or less. Measure the length of the choke assembly. Remove the choke from the carb and plug the wires into a 12V source for 15 minutes. The choke body should be warm. Measure the length again - it should increase by around 1/8".
Next, consider whether your exhaust pipe is clogged. This is especially a problem with older two stroke scooters. The unburned fuel/oil mixture builds up in the exhaust pipe along with carbon over time. If the exhaust pipe is clogged, your scooter will run terribly or not at all. It can be difficult to tell if the exhaust pipe is clogged. The easiest way to tell is to remove it and try starting your scooter. It will be a bit loud - two strokes will sound like a chain saw. If it runs with the exhaust pipe off, you know that is the problem
hope this helps

Sounds like the battery may be either low or shot. Place it on a trickle charger overnite to see if it will take a charge. Once you get the bike to run without needing jumper cables to keep it running, check the charging system. Easiest way to do this is to get a battery voltage reading with a multi meter before starting the bike. After the bike is running, place the meter leads on the battery and work the throttle to get the revs up to about 2000. Meter reading should be somewhere around 13.8 to 14.2 voltsDC. It not close to these readings, you have a charging system problem.
