i have a 2003 400ex with a slip on exaust, amr cdi and coil, 14 tooth front sprocket, 55w hid headlight conversion kit, trx450 front shocks,pro armor nerf bars, velocity air filter...... ever since i changed the cdi and coil the bike makes a weird noise when it kills cold... it only makes the noise sometimes.. it almost sounds like loose metal in the exaust header. ive checked it twice and there is nothing in the header.... i cant find out what this sound is and it seems to be getting a little louder over time... please help!!!!!
