In the manual, it should detail how to perform a fuel flow test. Usually, it is performed by shorting the valve cut relay which powers the pump on all the time. Do not short across the ground or you will fry your relay. On my bike, it is the black and white wires in the relay (green should be ground).

Little lesson on early V4 Honda fuel systems(82-86..yours may be different due to the redesign in '86):
1. The fuel cut relay is triggered by the coils. So it doesn't actually get a solid supply of power. It only gets it when the coils fire - in another words, only when the bike is attempting to start, or is running
(this is a safety feature to cut off the fuel pump in case of a wreck/fuel leak and the bike stops running. Otherwise, even with the bike not running, the pump would keep pumping gas until no more gas, or no more electricity, or no more pump {explosion}).
2. If this relay is bad, the pump will never get power.
3. The fuel pump is a really low pressure pump (like 3psi). So when the float bowls are full, the float needle closes off the fuel flow and the pump cannot pump against the gas back pressure anymore so it stops. As the fuel is used in the carb, the float needle opens and the pump can now overcome the gas backpressure.

When you turn the kill-switch on and off, some residual voltage crosses the coils. So you may hear the pump click. This is a slow method to fill the carb float bowls. I usually short the relay or provide power directly to the pump until it slows/stops pumping.
