Ninja kawasaki keeps acelerating itself why?
I have a ninja kawasaki ex-500 2001, and out of nothing the bike keeps opening the throttle by itself, it doesn't matters that I try to pull the throttle by hand, it keeps running at a very high rpm, also noticed the pipes coming out of the engine(downpipe) were very hot tot he point they were turning red by the heat. I cleaned the carbs a few days before putit all back and the bikes runned nicely. What could be causing this problem and how can I fixe it? Also the throttle cables open and close are new.
