I have a gs750e a 1983 as of now I have an 82 1100 GS CDI box on it I would like to get one of the stock ones or was wondering if a early model GSXR or teapot would work or are they all about the same I know they changed a lot from 82 to 83 was just wondering if anybody had any experience with this or if any of them would give me more power thanks any input would be helpful
