Q:I own a 2014 Kawasaki Ninja 300. When I am on the throttle, I hear a whistling-squeaking noise. When I let go of the throttle, it goes away. Wondering what that is? Is it a big concern? SHAWN BALON CYCLEWORLD.COM
A:Go back and look at whatever was the last thing you had apart. Modern bikes are super good, so chances are you or the last mechanic left something amiss. My best guess is your air filter or airbox is adrift.
