electric start not working have to kick start

[dedhed]

After stopping at the store i came out and it wouldnt start i had to kick start it lights came on but no turn signals and as i revved it up the lights would get brighter ( was told this is the rectifier)i took the battery to the store and had them charge it up got it home and the bike started fine came out a few hours later and it was the same thing all over.The guy at the store said the battery checked out fine i have no alarm on the bike was told this might be draining it and like i said earlier was told its either the rectifier or stator the bike is only 4 months old so im hoping it might be the rectifier as i can change it my self any ideas what is causing my battery to drain and what can i do to rectify this problem so it wont happen again.

Virtually all these little bikes have a simple shunt regulator. Often as not, its connected to the battery, even when the ignition is off. So if the regulator fails, it can easily draw down the battery. Get an amp-meter, and find where the power is going. Weird electrics on these chinese bikes.
