It starts because current flows easier in a warm battery. But any guessing about what the problem is needs to start with a charged battery, lead acid batteries need to be charged to 12.6v, if it won't charge to 12.6v, the battery needs replacing. It also sounds like your charging system may not be working right, which may have caused the battery to fail. With a charged battery check voltage at battery at 2500-3500rpm, it should read 13 to 14 volts, most bikes do not charge at idle.
If the battery turns the engine over as it should then the battery is good.
check battery
buy a new starter motor yours is worn out
your alternator ain't charging your battery or a bad connection draining the battery
check to see if battery is connected correctly. and correctly is positive cable to positive terminal
Sounds like you have a dead battery.
It is the ECC relay! It is the ECC relay!
Yes. The alternator is used to keep the battery charged, while using the headlights, radio, a/c, etc. The starter to me is misstated because it actually cranks the engine. The ignition system starts it, and keeps it running.
if i sccidently shorted the battery car wont start but cranks whats wrong ??
could be the starter or the solenoid, they arer pron to heating up especially when using headers, peace
Broken timing chain or belt
