CB750 '80-'82 DOHC KeiHin VB42's
The more common KeiHin VB42's with non adjustable floats. Basically, all the same carb '80-'82. The main difference being the '82 having a screw-out idle jet. Also the LTD has a combination of chrome and black anodized hardware. The list below is not super important because all these years can easily interchange with no changes. However, you may find it fun to see what actually goes with what bike.
