We are meaning the throttle plate closes faster when you let off the pedal. Therefore adding or adjusting the return spring is the only way to alter it.
Although I have never had a problem with slack in the throttle cable with the stock TB. (65mm needs those rubber washers though)
That is a good idea for taking up cable slack since the brackets are not adjustable.
