This small amount of coolant coming out of the weep hole is perfectly normal.
The rule of thumb on GS water pumps is that the pump is good to go unless you have to add coolant to the plastic reservoir which only holds about 3oz.
It is a fairly involved process to change the water pump and something that most owners would not want the dealer to take on unless absolutely necessary.
It is also a very rare event that a water pumps has left a rider stranded.
