Mr Bumblebee, would the wrong battery not allow a bike to turn over properly? The bike did not turn over, still the starter is engaging and thats that's happening. I took it apart and it seems to function fine.
If the cranking amps are too low, it will act very strange...

The batteries have to be strong in these bikes....

It could be your starter clutch...if the bike sat for a long time and things got all gummed up anything can happen.

Hey folks! New to this forum and very excited to be here. I just bought a non running 2005 Hayabusa which doesn't start, the starter on this bike just spins and doesn't crank or do anything. Also I believe the bike has been sitting for a while and will not go to 1st or second gear :(, any help is appreciated.
Check the voltage and with a meter at the battery. You need quite a bit of voltage before it will turn over and start. If the voltage is low it will turn over but not start. Chances are your clutch switch is the problem. Most bikes I dealt with it's the clutch switch being defective that allows the bike to turn over but not start. Chances are your problems are one of those two issues. They are easy to verify. Clutch switch can be jumpered to verify if it's the issue.

That would make sense, how the heck should I flush out the gumming? I was thinking about using Kerosene in the engine and flushing it out?

I hope it is the clutch switch , how do I end up replacing that more importantly, how do I jump that bugger out? A new left side switch?

Yeah it's on the left side electro mechanical switch. It makes a clicky sound. Take the two electrical wire connectors off the switch and put a piece of metal connecting them together. Then fire her up. You can't ride like this since it will give the ECU an error after a while and it affects the ignition since it thinks the clutch is being pulled in constantly. It's a good way to troubleshoot and if it works just get a new switch.

Do not do anything like that on a modern engine as it will create a viscosity that is below the minimum required. Pressure will be inadequate which can cause an utter catastrophe.

When you have repaired the bike and got it working well then merely ride it. You already cleaned out as much oil as you can which is perfect. Motor oil itself has detergents and inherently cleans whatever it touches.

Do put Seafoam in the fuel. That will clean up valves and such.

That does sound about right, hopefully I get it repaired.

Well guys I took apart my fuel pump and thats not poop you folks see^^. That is probably the by product of gasoline. No wonder I didn't hear a damm thing when the pump tried to prime. I purchased a new strainer and am currently cleaning the fuel filter (it is quite rusty). Also I am going to manually crank the bike to get some of the Marvel Mystery Oil into the cylinder walls so when I fire the bike up I don't have any issues. Any words of advice on anything before I do all this?

Get the fuel system completely serviced and get new injectors and fuel pump.

Hopefully the inside of the tank isn't rusted out...

You could take all the plugs out and spray a little engine storage spray in each hole-leave the plugs out when you turn it over-you could even do this by taking the engine case cover off and use a wrench. This will ensure there is some lubricant on the cylinder walls and rings...
