87 octane or 93 octane

I’m looking for some advice on fuel choice for my 1992 Honda CBR600F2. My bike was originally designed for 87 octane, but I’ve made several modifications and am wondering if it’s worth switching to 93 octane.
Here are the current mods on my bike
Jet Kit: 42 pilot jets and 145 main jets
(Carbs were synced and air to fuel ratio adjusted as well)
K&N HA-6091 Air Filter
Vance & Hines 4-into-1 Exhaust
Aluminum Radiator for improved cooling
I’ve been using 87 octane and getting around 34 mpg with a mix of hard riding and varied conditions. However, I’m considering switching to 93 octane and have noticed it might slightly lower my mpg to around 32.
1. Given the modifications, would you recommend using 93 octane for better performance or is 87 octane still adequate?
2. Has anyone experienced significant performance improvements or differences in fuel efficiency when switching to 93 octane with similar mods?
Thanks in advance for your insights!

The bike is designed to run on 87. Upping the octane will just empty your wallet.
However, @Ed Harris stated, go for the lowest ethanol rating as possible. I'm fortunate in that I live in an area where ethanol free gas is available. It's expensive but worth it in some cases.
