Hello all, I am having a problem with my 01 gsxr 1000. When i put the key in and turn to on the display comes on for a few seconds and then proceeds to make a pulsating humming sound from somewhere under the fuel tank. Whenever i try the ignition it also drains the battery fast. I’ve replaced the starter relay and that didn’t seem to fix the problem. I also get a constant clicking sound when trying to start it at the same time as the humming sound. If anyone can give me any pointers it would be greatly appreciated. Thank you.

Humming under the tank for three seconds is the fuel pump priming. Clicking could be the starter solenoid but it could also be the EXCVA servo, or the STVA servo. Where is the clicking coming from? Raise the tank before you turn the ignition on to better identify the source. It sounds like your battery is done for.

I believe the clicking is from the starter solenoid but I just replaced it so I don’t know if it would be that. I have a video of the noises that it makes when I turn the key on I will attach to this reply. The bike was sitting in a storage facility for 4 years so I don’t know if that has to do with it either. I also have never worked on a motorcycle before and I have no clue what I’m doing so thank you for your help. Starting Noises

What's your battery voltage?

What's your battery voltage?

When the key is in the off position it reads around 11.95 volts but when i turn it on and the stuff that happens in the video after that it reads about 11.75. If i try to push the ignition while it does that it practically drains the battery

A fully charged 12 volt battery is 12.6 volts. There are 6 cells, a healthy cell will make a little over 2.1 volts.
11.95 is discharged. You might be thinking to yourself...oh it's close enough to 12, it's good enough...however, it's closer to being only about 20% of its strength.

It's hard to properly troubleshoot your electrical system without a good battery...charge it / replace etc.
That clicking noise is the starter relay's way of telling you, the battery is pooched.

Anything can fail but starter solenoids are fairly robust. Good chance that the one that you replaced was OK.

+1 on the battery being dead.

"If i try to push the ignition while it does that it practically drains the battery"
If you're monitoring the voltage while it tries to crank, it should drop a volt or so due to the draw through the starter. More than that is a toasted battery. What's probably happening is that the solenoid closes, the starter draw drops the voltage way down, there isn't enough voltage to keep the solenoid closed so it opens, the voltage recovers, and the cycle repeats. Hence the clicking.

As you're new to bikes, don't jumper from a car. That's too much for the bike's electrics.

With that information, I’ll pick up a new battery before further testing. Is there anything particular about the battery i should be looking for besides it being a 12v battery?

The original was a Furukawa FTX12-BS. They're essentially unavailable in the US. A good alternative is a Yuasa YTX12-BS, around $75. Off brand batteries from China are cheaper but don't last very long.

Update: Picked up a Yuasa YTX12-BS battery and it charges up properly now. I try to start in and it’s cranking over now but still doesn’t want to fully push over. My step dad and I pulled out the spark plugs and he said they looked good the only thing is they weren’t wet with gas so it could be a fuel system issue? Took another video that i will post with this. Thank you guys.
Crank but no start

Try priming the engine by putting a couple cc's of gas into each throttle bore and see if it will briefly run.
