The bike wont like running cone filters , you will be in hell for sure.
Though you can make a metal box , fabricated , then cut 3 holes (2 for the carbs and use GT125R airbox rubbers) and cut other hole for tube custom flexi hose to connect to the air-filter box on the side of thebox Thats what some people do now. Costly but least with a custom metalbox, you never have to worry about the plastic airbox ever again.
Besides hyosung isn’t making new ones anymore. They moved on to EFi GV125 Bobber models now.
