Bogs down at about 35 mph

[CBonafide]

Hello,
Recently my agility 125 dropped out while riding. It starts, idles fine, but when I give it a turn of the throttle it bogs down and chokes. I thought it might be the CDI but I had a new spare and tried it and nothing changed. It runs smooth if I feather it up to 30-35 mph then it bogs down. I cannot detect any type of vacuum leak either. Gas is clean, got a new plug wire, new CDI, anybody got any idea?

-open fuel tap
-you might look into your carb whether all passages are clear
-check vacuum fuel pump and hoses for demage and functionality/tight fit
-Inspect this diaphragm in your carb for tiny holes in it
-take the airfilter out to see if clogged

Don't know if this is useful, but an old stator will cause your motor to repeatedly "bog down" at constant cruise speed. Just slightly, but enough to be annoying. You'll need a flywheel puller to get at the stator to change it. Takes about an hour to do the change.
