I have a 1983 VF750F which has sat in the garage for 20 years. I rebuilding & replacing anything that needs to be fixed. My question is does anyone know what is the seal size for the crank for the left side alternator. I had oil inside the alternator cover which I cleaned but when I push the bike around oil pours out of alternator location. This leads me to think it is the seal. I have looked in the Honda service manual & Clymer book which I have and can't seem to find this info. Thanks for any help you can provide John Hamilton
