I recently picked up a 1971 CB750 that had been in a field for the last 15 years. Only thing missing was the turn signals. It turns over with the kick start and the compression is very low on three cylinders. The vin's are CB750E-109441 for the motor and CB750-1094087 on the frame. Does anyone know what the 9 is in both vin's, (since I live in Canada, could this be a Canadian bike?) Anyone have any answers. Thanks.
