So I had an 81 goldwing did I purchase really cheap. It needed some TLC so I purchased a 1980 for parts. While trying to start the 81 I heard a whirring sound. It was the starter not rapping out. I sent to change the starter but the chain inside felt very loose. since I have put in a starter in bike starts right away but there is a clunking sound coming from inside the motor somewhere. When I drain the oil there was an abundance of oil it was mixed with gas. I refilled it and change the spark plugs with the required amount of oil. The clunking still happens though not as bad. Any ideas as to what this might be?
