Sounds as if you are running dry on your run.
Raise the float up a bit try #95 jets, Needles on bottom rung.
try 87 or mid octane for a hotter burn
The 93 is sometimes the problem lower btu's per liter.
if you have not advanced the timing. try it.

up though it'll chug along fine when warm.

The Carb is perhaps too rich have you tuned the air/screw mixture
to balance each side.

Subject: [CB175RaceTech] Still having issues
After 900 miles or so on my cb175 and countless adjustments it still
seems to have a couple of issues I'd think. Will pull just fine
through 3rd to 10k rpm, in 4th it'll pull to about 9 and change. 5th
about 7-8k. On the highway I can coax it up to about 60-65mph then
when I go to 5th it'll end up back around 50mph or so. Plugs still
have some carbon build up after a ride. Have the carb needle as far
down as I can adjust it. The floats are right where they should be,
running 98 main jets. I did try some 92s that were in a spare carb and
it runs out of gas above 5k. It definately runs better before it heats
up though it'll chug along fine when warm. Just doesn't seem to idle
as nice, etc. Compression is around 140 each side (my gauge isn't the
best for this engine). No need for the choke even when starting cold.
I am getting around 50mpg using 93 octane. I weigh about 225lbs. I
seem to have a slight oil leak out of the one side of the head.
Haven't figured out where though as I just see some oil on the fins.
