My raptor 660 ran out of battery, I conected to the car battery and it turned on, but after that, its not starting. The raptor starts, but the engine wont start running. I checked the spark plug, it does create a spark randomly, I don't know if its sparking at the right time. But I dont know why the engine wont start running. Do you know how I can fix this?

 

try putting gas in it hahaha j/k

 

We need to know more of what is going on before anyone can help. You said you started it with a car battery and it started, but now it doesnt start? Did it run fine before you started it with the car battery? Does the starter turn the engine over? Have you checked your carb boots, fuel lines/levels, made sure you were in neutral, checked your oem battery's voltage/condition, etc? Is the plug fully seated into the head?

 

Be careful! You might burn something up using a car battery because it has too much juice for the smaller starters on motorcycles and ATVs. I know the Rapter takes more juice than the Eton 90 but when I tried that on the little Eton it started frying the wires to the battery. I also used to have a streetbike and was warned about the same thing. Hopefully you didn't do any damage.
