your lucky the ball cup has never popped off the 5 port, unless your using the smaller ball cup on the Vspec.
when I first ran the 5 port, I had to put a ball cup from the GT2 linkage on my RC8, because it kept popping off the Go carb. when comparing the vspec and Go ball links side by side they (GO) are smaller.
