Mikuni Bst 31 Does Anyone Know What Aftermarket Carb Would Work On A Polaris 325 Magnum Atvwith A Mikuni Bst 31?

Does anyone know what aftermarket carb would work on a polaris 325 magnum atvwith a mikuni bst 31? - mikuni bst 31

I have a 2001 Polaris 325 Magnum 4x4 with a carb that BST31 Mukine. I called the dealer and reseller of aftermarket Polaris ATV parts, but I said, it was converted into a car for Mikuni BST31, I asked for another model or brand to replace one I only get on the phone, or a blank stare from the counterparties person.I just want the will of another model bolt Mikuni carb on my machine know, silence, either without or with very little Modifaction? I am not willing to pay almost $ 400.00 for a new BST31, or nearly $ 200.00 for the reconstruction of parts of the proceedings. I've seen that other Mikuni carbs more supplies, offers such as VM, TM and Mikuni uniform around $ 175.00, but do not know what I got my machine a fuel pump and tell me, means that the need for a needle in 1.5, but do not know what carbohydrates, MM or aircraft is also required if the carburetor needs a new accelerator pump.I myself think, because carbohydrates cable is not available when the plastic covers on defense. Thanks
