How to tell if I have the right carbs?

[Moose]

I figure this is the best place to post this question, I have a set of twin carbs that came with my GS but I am not sure if they are the right ones.  I can tell you that they are Mikuni carbs and when you look at the opposite end of the floats it has on the flaps 135 with a square symbol in front of the 135.  I know this is probably a question that seems ludicrious, but we all have to start somewhere.

remove your carbs from the bike and compare!

I think there are some pics on pantablo's and JeffD's website along with some on the main gstwin.com site under the howto/maintenance section

Well it looks as though I have the wrong set of carbs.  The bowls look different and so do the opening where the air jets are.  Which really stinks.  :x  So I guess I will be on the hunt for a set of carbs.
