Definately the first thing to adjust, but do this in very small increments. If it starts to sound like the motor is trying too hard or the sound gets louder and high pitched, then go back, you've gone to far and can wreck the pinion gear on the motor.
If this doesn't help you, the new systema motors that Harley has recommended (Magnum, Turbo) will reduce the sound somewhat, they are the newest and currently best in AEG motor technology.
Also, if you increase the ratio of piston bang to gear/motor whine noise, it helps your mind accept things. If you can get an inner barrel that goes out (very slightly) into the flash hider instead of ending inside the outer barrel, the 'bang' seems slightly louder. Ball bearing aluminum piston heads also increase the racket at the risk of damaging the gear box. Also along these lines, an upgraded spring will make it louder as you go up in rating, but going this route, I would recommend a silent piston head ironically. They don't really make it quieter, but they protect your gear box from some impact. Mind you, I think CA's are already upgraded over a standard Marui, so use my last two suggestions at you own discretion.
