the gold tubes and black rubbers are your carb heaters, they are designed to divert some hot coolant to the back of your float bowls to increase the temperature of the fuel by a few degrees to prevent the possibility of carb icing occurring when its cold, humid and you are on full throttle.

only seen on bikes where it is a possible occurance, most people remove them, ive never known of one credible occurance of carb icing on these bikes, i thought i had it, but it turned out to be poor mixture control.
