As someone who has parted out a couple bikes, it can be a pain in the ass!
Plenty of people who want to pay next to nothing, flakes & other's just wasting your time. It takes some patience and packing and shipping stuff out can be very time consuming.. I would consider this 1st and foremost, do you have a buyer for the frame & motor already? if not those 2 parts are not easy to sell and high value and high price on shipping.. nothing worse than being stuck with large items that take up space and in the motors case, if not sold locally, you will have to take to a shipper.
