Set it slightly lean and the. Apply the choke a little at a time. If there is a power increase then go a tad ritcher. Repeat. I do it for WOT and for cruise. Pilot circuit ( cns) is bit finiki though.
That's one thing I like about the CNS carb is that it has an enrichener circuit like most motorcycles have and it's a good tuning tool or if you need an emergency cool down you can just feather the choke enough to give it that little extra it may need on a really hot day or right after a hard run.
