Hello, which bike is it?

Usually you have to remove the throttle slides from the top of the carbs to get to the needles on most setups.

This would normally mean removing all the components above the slides to get access, then replacing afterwards.

Can be done in-situ but marginally easier if carbs are removed and worked on seperately on a bench.

It's a bit fiddly but not too bad if you have a bit of time to get it done.

Hope you get it running a bit smoother with the adjustment.
