I'm a new member. 70 yrs old...have 8 old bikes...been maintaining and restoring forever. Presently restoring a 1974 Yamaha g7s 80 cc cafe racer that has been in the family since 1975. Just got it back from my sister...it suffered from brutality by kids and sitting in garage for 15 years. I desperately need an ignition switch. I purchased an fs1 switch hoping I could use it but it is short one wire. I have a mechanic's manual but the wiring diagram is not helpful. Have tried all the normal sites such as ebay ect. with no luck. Any help to find parts like this?
