Funny you should ask, as I'm swapping out my Motion Pro bottle for a custom made job. Currently in the process of finding the parts to make the hose attachments now. The lid on my Motion Pro bottle leaks and spits water onto the inside of my screen and my face shield every track day.
Swiped this pic off a friend from another forum. I can get you a pic of my setup as well if you want it, but this is basically how I did it. Simply go to a big-box hardware store and pick up a piece of aluminum flat bar, cut it to size, bend it to hold the bottom of the bottle in place, zip tie the bottle to the piece of aluminum, and mount aluminum in the empty holes left in the fairing stay where the lights mounted. (Which I assume you've done already).
You also have to pilfer a the right-angle hose attachment from the stock coolant bottle lid to make this exact setup work.
