Welcome to the forum.

You don't say how much you are riding the bike between starting it. If you just start it and let it idle a bit, it will never recharge and eventually it will kill the battery.

First thing is to charge the battery, start the bike and check the voltage at the battery while it is running at about 5k rpm. It should be a bit over 14 volts.

Let us know what you find.

As far as your comment that the starter sounds strange, put a test light or voltmeter on the power wire lug at the starter and confirm it is not getting power when you release the button. Relays sometime stick ON with cars but I've not heard of that happening with these bikes.

I will have to go and purchase a volt meter and check. I just let the bike idle a couple minutes to warm it up and then turned it off. Turned it back on and I could tell the battery was a little weaker that when fully charged. Ive been riding GSXRs for years now and I thought it sounded different the way the starter sounds. I will try to record me starting it so you can see what it sounds like.
the previous owner says he had LED lights on it but removed them. Not sure if he messed anything up with that

The charging system barely has enough capacity below 2-3000 rpm to maintain system voltage. A start takes a lot more out of the battery than the charging system will put back in 10-20 minutes of idling.

BTW,starting the bike without riding it just makes a lot of moisture in the engine and promotes rust. It really does not help. You are better off changing the oil at the end of the riding system, put in some fuel stabilizer and leaving the bike alone. A battery tender helps.

This one with battery fully charged. Notice the sounds it makes after starting

This is after turning off and turning on after getting to my friends house

Listening to that, I would say you have a bad battery.

Put a voltmeter on the battery while you crank it. It should stay above 10.5 volts. My guess is you will see much less.

The battery was replaced twice. Fully charged and tried it again.
did you hear that sound im talking about?

No, sounded normal to me.

I'm totally lost. It sounds like a bad battery to me in the first vid and it starts great after you fully charged the battery.
