pz30 setup?

Does anyone out there have their jets worked out for a pz30 carby at sea level? I've mucked around a bit but it would just be easier if someone else told me their great setup and I used it instead. I wouldn't even claim the jetting as "my own hard work" if it works well. Whoever gives me the sizes will be mentioned in all conversations with my riding buddies. By the way, it's on a cb250 air cooled ohc engine. Don't know why they call it a 250 when everyone knows they are 223cc but oh well.
