i seen a youtube vid about this guy's moped not getting full potential unless his carb slider is all the way up in WOT. but his carb was the standard style carb.

mine is keihin cv carb, so somehow the slider goes up with the rubber diaphram

heres my question, i seen my slider only go up 75%, how do i adjust this to make the slider go all the way up?

its not the cable, cause the cable is pulling the throttle 100% the cable cant pull it any further. just the diaphragm isnt pulling it all the way open.

That works off vacuum. How do you know it is not going all the way up?

Remember it's vacuum verses spring pressure.

Take the carb top off and gently pull out the slide,,,, look at the bottom of the slide where the needle comes out ,, let the needle drop out, you will notice a second hole next to the actual needle hole ,, get a drill the same size as the "extra" hole and drill another hole on the opposite side of the needle hole,,, you will get quicker throttle response and full wide open

once you take the filter off you decrease vacuum.
