I recently bought a 96 gsr (all stock) and i drove it for two days now. When I went onto the free way it made a sound....(like a parrot) (wakk wakkk)... then it stops when i come to a stop. It only makes the sound when i reach 40 miles per hour but ten minute later it started to make the noise sometime when i'm driving at 35mph. It souds like it is coming from the front driverside of the wheel but it could also be the engine. It sounds like metal grinding on each other...

Do anyone know what is the matter??? Any advice are greatly appreciated..
