Ventus Ryuga Primary Chain Conversion Kit

you have me the wrong jack shaft sprocket but the one that goes on the motor is rite. I ordered what your site told me to order. It says that this kite is for the ryuga motors only and I have a ventus evo. now I have to wait some more and I also paid an extra 30 for shipping that is for absolutely nothing now. please tell me what to do with this sprocket and please send me the correct sprocket with bolt pattern.
