Advice on this Kz550

I tried getting them on a few different ways from both the left the right, coming from the bottom,top and at a angle. I meant the screws used for bench-syncing the opening of the butterflies. I'll give it another go when I have the time and try to get the carb into the airbox boots first. It is highly likely I might be having a bit of a clearance issue due to the frame. It would be great if that company makes them for the A4 model.
