For my 650 with pods and a slightly more free flowing exhaust I'm running the stock 15 pilot jets and have upped my mains to 115s (although I'm thinking that 112.5s would be a better match). But still, the mains are several sizes over stock jetting.

You need either a 140 and a 70 jet as per wiredgeorge or a 137 and 62 as I did.
Call Z1 Enterprises for the jets. Dont throw out that original airbox just yet....just in case you have problems finding the smaller jet.

Is it a 750 twin or 4? From all my experience with airbox to pods you have to rejet to allow more fuel. Of course, I've only ever worked on the mikuni vm24 carbs on the kz650s. Not sure about CV type carbs, but I would imagine that they'd need rejetted the same.
For my 650 with pods and a slightly more free flowing exhaust I'm running the stock 15 pilot jets and have upped my mains to 115s (although I'm thinking that 112.5s would be a better match). But still, the mains are several sizes over stock jetting.
I have a 650-4 with pods and freeeee flow exhaust, meaning no insulation just a metal baffle at the end for coppers:evil: . I have 15 pilots 110 mains. I'm thinking of takeing wiredgeorge advise and throughing the 17.5 back in due to I never adjusted the air bleed with the 17.5 so it ran rich at idle, but man did it respond hot and cold, and cold staart was a breeze.it ran good just smoked a lot. So I put back in the 15 pilots.

Sorry to get off topic, but ...The problem with sticking pods on the 750 is that the big BS series carbs contain little tiny main jets that are screwed into the float bowls.
George,
How common is it that the Jets get stuck in the bowls?
On my carbs, someone must have buggered the top of the jet with an improper screwdriver size or something...
But I figure, I'll keep the airbox, the jets will never have to come out..
Also, where can I buy new floats for BS carbs?
my brass floats are leaking like the titanic..
:dry:
