Welcome paw! Mike's right, go to your nearest Kymco dealer and to add, the Pulsar's engine are similar to the generic Hondas 125 and 155, so if you can't find a Kymco dealer you may try other motorcycle service/repair shops and ask. You may want to take pictures of side, front and under the engine where, for sure, the drain plug is situated.. to show to a mechanic...
