i havent tried 28mm carb, but you can buy one jet size at a time.
also follow the tuning manual of carbs here

sunworld, really drinks gas. mine's 28mm sunworld can accomodate only 60kms in 1 fulltank even i rejetted it already. I plan to change it to different carb. Was your head fully stock or ported cause as what the other thread told is the last safest bore for fully stock head was 59mm


tnx newbie here
