Don't know what bike you have but I would suggest you download a manual. Look in the stickies in general disc. This site shows how to do a jet replacement on a 1100 but the process is the same to get the carb out, apart, and back in. Good luck! The Sabre Group Tech & Mods
I remove all accessible rubber parts, all jets and adjustment screws, floats etc and soak the bodies in a 50-50 mix of pinesol for 24 hours or so.
Make sure you remove the very small washers and o-rings under the idle mixture adjustment screw. Than I blow out every orifice with compressed air. Make sure your rinse the bodies well with warm water. Than I polish the float needle seats with brasso on a q-tip.
I take the removed jets and soak them in carb cleaner. These are the only parts that get touched with carb cleaner when I rebuild carbs.
Re assemble, inspect the float diaphragms, inspect the float needles, set the float height, and bench sync. I also fill the bowls on the bench to give a good leak check. Nothin more irritating than installing carbs and having them spit fuel all over the ground...
