'82 KZ1000J2 @1100cc - jetting question

Howyadoin,

I'm making another attempt at getting my Eternal Project Bike running again.  I've got a shop working on the bike and they are trying to figure out the correct carb jetting.  The bike was worked on by another shop back in the 1990s who punched out the cylinders, I'm told to 1100cc, and did a valve job.  The bike also has a V&H 4-into-1 pipe.  What would be a reasonable jet upsize from stock, given these parameters?  I'm keeping the stock airbox and filter... I've been burned by pods and CV carbs - never again!

Thanks!

What carbs are they?

Sorry, should have specified...  They are BS34s.

So I went digging, and figured a jet kit would give some flexibility in tuning.  Given the engine has increased displacement to 1100, a valve job and a V&H 4-into-1, I'd imagine a Stage 2 kit would be a good choice, but I can't seem to locate one.   Looking at Dynojet's offerings, I see only a Stage 1 kit, or a Stage 3 that is meant for running pods (yecch).  Any suggestions?
