I've just had the same problem with the carbs. Pretty well impossible to remove still on the manifold as the heat shield is in the way of two of the retaining nuts for the manifold.

However, it is no big deal removing the carbs even if the lower nuts are a bit difficult to get to. The interconnecting links will drop out but it is pretty easy to put them back in. I hope the next pic shows the info you are looking for, in as how they go. I'm only back on the road last weekend.

I took pics as well as having manuals with the info in them for future reference.
