the carb. may be running on the off idle cucuit, because the throatle is almost closed. This cucuit is for first gear starting and is not all that good for sixth gear...
You may be having the same problem. What I have desided to do is optimise the final drive to keep the GS500 above 3500rpm, in 6th gear, at highway speed of 65 - 70mph, until I can come up with a better solution. I am day dreaming about a single carb setup with my own intake manifold.
