Jet sizing and buying

[TDub77]

Hey all, I'm looking for some advice on jet sizing.
I have a 1980 Honda CB 750 K. 4 to 2 exhaust and I just put on pod filters. The bike idles fine, maybe a bit rich (there's some backfiring/popping) but at high RPM's seems like it's getting starved of gas. My current jet sizes are 102/ either 68 or 89, I can't tell and it's the most frustrating thing ever.
I know with both the 4 to 2 exhaust and the pod filters I should run larger jet sizes, but how large? One place online I saw said 110/75. I'll be calling a dealer monday to see if they have any suggestions.
Also, where can I buy jets? I haven't really found anywhere online yet. Once again I'll be calling a dealer on monday to see what they have.
Thanks

Do a search its has been discussed many times on here, but your problem is the pod filters, you will have a hard time getting the jetting correct with pod filters.
