Generally, on these BST33 carbs, the left air jet is for the main circuit : main jet /needle jet = 0,6m/m - the right one is for slow jet circuit = 1,3 m/m. Even if using a 0,5m/m guitar wire : NEVER probe with a steel wire !! 'cause It's harder material than the parts made of brass :((
Compressed air is your friend, poking with wire is never a good idea when cleaning carb ports &/or orifices. Removing & ultrasound cleaner is better still.👍
Yeah I didn't have a can of compressed air at the time, I think that bike had compression issues or something because it just never really ran right...
Keep watching my videos, it gets better 😂 if you’re still having problems with your motorcycle, I recommend Reddit, also ChatGPT is actually pretty smart these days
