I'm having problems with my cbr250 but being a NOOB when it comes to bikes i dont know whats wrong or what to do. The bike feels down on power, it just doesnt pull like it used to. The power drop hasnt been gradual, it just happened after a day or two outside in the rain. Could that have caused the problem? I also recently painted the engine and everything else matte black a couple of weeks ago, could that be the cause? Any thoughts & suggestions?
