I have a 1978 F2 CB750. The bike cam with the two helmet decals attached to the frame adjacent to the helmet holder hooks. The decals had been painted over so after I stripped and painted the frame I applied new decals in the original positions. If you look very carefully on page 5-4 of the service manual you can just see the bottom edge of one of the decals under the edge of the seat. The service manual can be downloaded from this site. The approx. size of the file is 35MB. Pat
