How do you know that your charging system works? Basically, if the voltage on the batter reads above 13 when the throttle is twisted?
It's a chinese clone of a Honda, 49cc. Just trying to determine whether the batter is the problem or not.
For about $10 or so, you can get a 6 LED monitor, where
each LED lights up at a specific voltage (12, 12.5 ...14).
Find a point in the wiring where there's voltage only when
the bike's turned on and hook up here. Makes a very nice
monitor while you're riding and gives you full time info
on how the charging system's doing.
A good starting point in your troubleshooting would be to
get the battery charged and load tested. After it's charged,
you should see it holding 12.4-12.5 volts or so. If it can't
hold this kind of voltage you may need a new battery.
Also, take a very careful look at the battery cable connections.
A loose + or - cable can fool you into thinking you have a
bad battery or charging system.
