I think the Korean’s did a very good job with Mukuni Japan to make a “custom DF series” pump for Hyosungs.

The GV250 uses the same pump as a GV650 carby = it means the GV250 will not be able to max it out.  The vacuum pump is poweful enough to run a 650cc already.

If it has problems, you can replace it (but they rarely fail except bad debris from fuel , crap fuel (e10) ,  or just simply very old age kicking in)

An electric pump would put more strain on the stator unit and the regulator because the regulator sits “under the seat” , it does not get enough air cooling , compared to a GV650/GT650 to cool down the regulator.

The “floats” for the carb can’t handle anymore extra psi , henceforward the “vacuum pump” works in  “pulse fasion” , it pumps more as the carbs demand more.

For “simplicity” and efficiency , i would recommend less electronics on a carb bike ,  after all the stator it uses has less watts than an EFi model and it also has less poles than an EFi model.

The EFi models use electric pumps but they have updated stators to handle it and a 30A relay dedicated for a pump, it is resource hungry.
