I recently bought an 01 WR426. The bike is super clean...it passes all of the basic tests...very little peg and rotor wear (stock parts), wheel bearings are solid, no leaks of any kind, no smoke, etc. However, it has a chirp during accelleration. A guy here at work that has been riding offroad for around 40 years suggested that it is air flow into the carb, is that true? I have never heard of this issue. It has the air box cover removed and the exhaust has been opened up.
I searched the forum and found very little information on this topic.
