Hi and welcome to FixYa,

If the starter motor will not turn, a few ideas to consider:

• the starter motor is actually switched by the starter relay. The starter relay is switched by the start button;
• on pressing the start button there would be an audible click, that would be the starter relay;
• the starter relay will only work if the sidestand is down, the bike is in neutral and the engine switch is on. These are the interlocks/safeguards;
• to locate the starter relay, follow the cable from the + terminal of the battery;
• press on the start button, the starter relay should click;
• if starter motor will not turn, jumper the two big terminals of the starter relay using a wrench. Do it on the nuts not on the threaded portion;
• if the starter motor engages, then the starter relay is faulty;
• if there is no click from the starter relay, either it is faulty or any of the interlocks is preventing it from working;
• if there is click but the starter will not spin and then will spin when the terminals are jumped, then the contacts of the starter relay are faulty;
• if even jumping the terminals, the starter motor will not turn, then it wold be a defective starter motor, most likely the carbon brushes.

from your description, i would sugest you make sure fuel is getting to the injector unit, remove the fuel supply hose.if you have spark at the plugs and fuel getting to the injectors you have isolated the problem. i would also drain the old fuel when you take the hose off and fill the tank with high grade fuel. bikes dont like old gas.

it may have snapped in the middle of the cable or check the drive in the front wheel
