I have a 2007 ninja 650R and I whiskey throttled it popped a wheelie and ate gravel the bike kept moving then slowing stopped and fell over on its right side. I don’t have any fenders on the bike so it hit everything only thing visibly broken was coolant reservoir which I’ve already fixed and flushed the coolant. The rear brake pedal is bent in just a little I have a new one just haven’t put it in yet, the front brake lever is bent just a little too but the brakes are working fine. After working on it today and finally riding it again I’ve heard a rattling noise when in the lower rpms. I don’t know if it’s there when I’m driving in the higher rpms because I can’t hear since the bike is so loud. But when slowing down I definitely hear some kind of metal scratching/rattling. What should I be looking for. I need an oil change idk if that has anything to do with it. It does not make the sound while in neutral and revving.
