1993 Honda Goldwing GL1500

parting out a 1993 Honda Goldwing GL1500 aspencade. bike is in great condition but needs new alternator and motor might be seized, bike was running fine last summer until my alternator went bad, I tried to replace it myself and it ended up not working. I brought the bike into a mechanic to replace alternator and they ended up telling me that there was no oil and the motor was seized witch made no sense to me as it was running fine before hand, I regularly check my oil, and the bike had no oil leaks. as of now I have purchased a new motorcycle and have given up on the Goldwing. no parts have been taken yet so let me know what you need, or if you want to buy as a whole
