Honda came out with 3 models in the 1978 Hawk. One was an economy version with a kick start only and wire wheels. The other standard shift (I donĀ“t recall the designation) was similar, but with the electric start and the comstock wheels. The Hondamatic (CB400A) was similar to the last mentioned bike (electric starter and comstock wheels), BUT, it had different size carbs than the other two, to somehow accomodate for the torque converter transmission. Hopes this helps.
