Battery cables first check. Then a good charge on a low amp maintenance charger. Then voltages checks.

Then remove battery and a CCA check of battery on a good machine designed for the small bike batteries.

PS.. Welcome to the HDFORUM.

Any mods to the engine and when did this start? When did you buy it? Interesting that even if a bad battery or loose cable, that it would still start cold.

Note that he said won't crank. Battery stuff mentioned in post three is where one starts to eliminate the basics.

If that was good, if I heard a relay click, I would check starter solenoid .

However, we don't even know if we are dealing with a Moped or a Harley with a BCM.

It's winter. Let's just play along.

Poll is good. Both choices work. I checked.

I agree check the basics. But I just find it interesting that it would crank when cold, but not hot, on a stock motor. Which we don't know. Maybe some big high compression motor, which I have no expereince with and he is not using the compression release, because he just bought it and doesn't know they are there? Even bad electric compression release on a stock motor, should allow it atleast do something.

Maybe first thing I would do, after tighening cables, is put a jump pack on it and see if does more. or charger on high just fort few minutes. 6-10 amps high, not some monster.
