Carb set up advice please.

Hi guys

My GS1000 is fairly standard apart from a flowed head and 3 angle cut stainless valves.  It has a one off exhaust which is big bore and nice and free flowing.

I have CR33's fitted which are only a year or so old.  The bike is running very rich, the end of the pipe is black and requires no choke to cold start.

i am looking for any advice on a base setting and jet sizes, any help would be great.
