I've got myself a Star M4 that I'm looking to get to around 400 FPS

I currently shoots around 270 FPS so yeah... I'm sure there are some tired parts in it.

Any ideas where I should start.

Also any idea what this gun should be shooting with a 9.6v 1600 Mah battery in it for Rounds per sec/min.
Just curious to see if the motor is worn out perhaps.

Thanks,
Wesley
