Hi everybody. Im new here. I own a ninja 636 from the 06'. My ninja has a problem. And i have no idea what it is. This is what happens. It turns on like no prob. But rpms are very low untill it warms up. Then it is fine. I cant raise the rpms when its cold because then when it warms up it will be to accelerated. Second problem. It runs no problem for about 1.5 hrs. And then it turns off. Then i have to wait untill it cools down so i can turn it back on. Why this happens? I replace recently the spark plugs, clutch, and the clutch sensor. This sensor is made of copper and gets smaller by tbe friction so its got to be replace or it will do what my byke does. But that did not fix the problem. :-( why god? Why cant i fix this problem? Help please. Help!!!!
