Any older cold blooded Rockets other than mine?

A french fellow had have the same problem , Mexican !
He thought it was a battery problem as you do .
He got the idea to check the fuel pump . The pressure must
be 3 bars and he got only 1.9 bars . He tested the pressure regulator,
it was ok to 3 bars so he changed the pump and now it's OK .
Perhaps you should test the pressure on the ruber line before the
injectors , with a T on the line and a manometer that would be useful .

The issue with mine was that when you hit the starter button it just clicked, or maybe turned over once then nothing. It felt more like a dead battery, if it would crank and not start that would be more like the pump, i think

Does the fuel pump whirr and the dash light up when you turn the ignition on, but the dash go out when you hit the starter button and get the click?
If si it's 100% the battery. The only question is why.
You can test the bike's charging system with an multimetre to check it's delivering full output. If all is good, you can charge the battery disconnected and if it retains full charge 24 hours later the battery itself is holding a charge. If when reconnected to the bike it is still charged in another 24 hours, there's no parasitic drain through the bike via a leaky earth.
Try putting a multimetre on the battery while the starter motor is being cranked. If the voltage drops drastically the battery's capacity has been depleted and in high stress situations, ie. very cold weather starts or when the bike and battery have become very hot after extended slow speed riding etc, your battery is goosed and needs replacing.

My 240 build is cold blooded, too. Refuses to start when the temps are cooler.

I just had this issue, Lupe, in sunny Florida. I changed the starter relay. ( not the 30 amp fuse) and all was well. They're cheap, like $10 on Amazon, if I remember.
