Let me start by saying hello

I got a 2006 ninja 650r for fathers day and oh boy has it been trouble. First the battery was dead and reading the forums i decided to replace it.

I ordered a new starter relay/ junction box because when i am trying to start all i hear is a loud multiple click. I have tried jumping from a known good car battery obviously not running.

But the real issue i noticed today is that i tried turning the crank and it only moved a little to the right and then i could move it a little to the left. So i decided to pull both covers to see what was going on inside. And of all things murky brown oil..... I figured head gasket but wanted to make sure.

I poured some coolant into the radiator and it came right out the stator side :/ need some advice. I am mechanically savvy but new to working on bikes. Please help so i dont have to rip apart the whole engine..
