jets in relation to chage in displacement

I am rejetting my 77 kz650 that I have just rebuilt, and have one question.
I have read all of the stuff in the files here and it has helped tremendously, but still one question remains.

There are the basic formulas to get a starting point for selecting new jet sizes, based on intake mods, and exaust mods. (example: 1point for high flow filter, 2points for pods etc) But there doesnt seem to be any consideration for change in displacement.

here is what I have:

K&N high flow filter in stock airbox.
4 into one V&H pipe

according to the liturature this should give a new jet size of 2 sizes above the stock, and no change in pilot.

But this has not taken into consideration that I had the cylenders bored 0.5mm over, and new pistons. I beleve this changes my displacement from 652cc to 662cc. It doesnt seem like much, but shouldnt this be considered when choosing new jet sizes?
What does anyone think, One more size? Would this be too much?
any help is much appreciated.

that small of a change in displacement should not have much effect on how the bike run's after all it is only a 2.5 cc increase per cylinder after all not much of an increase percentage wise is it. what will make more difference are the induction system and exhaust that you are using.

How about a larger jump in displacement, 25 cc or more per cylinder?
Thanks
