Cap the #4 intake stub with another vacuum cap same as fitted to carbs 1 - 3, or cut the AIS pipe, leave it on the stub and plug it with a bolt.Plenty of bottle tops are a similar size to the airbox stub. A dab of silicon and you're sorted. While you're looking for one to do the job, duct tape over the stub will do the trick temporarily.
I've had mine done but can't remember sizes, Justy1000 sourced all the bits so I'll text him and maybe he can tell you in a little while?
