To remove stuck float pins this is what I do;
1) Grab one of the float pins you've already removed
2) Lightly hammer that float pin into one of the float pin holders this should slowly push the stuck float pin out.
3) Once the non-stuck float pin is partially through use a set of pliers (one side on the end of the float pin, the other side on the float pin holder) to push the free float pin in and the old stuck float pin should fall out the other side.
To remove the main jets
1) Soak them in WD-40
2) Scrub down the main jet and the main jet holder
3) Soak in some carb cleaner or simple green if you have it
4) Use a hair blow dryer to heat the area
5) Use some pliers and yank
To remove the slides
1) Remove each carb from the carb rack
2) Fold down the locking tab on the nuts that have the arrows pointing to them
3) Unscrew the nuts that have the arrows pointing to them
4) Bring the slide arm up by pulling up on the levers/nuts that are circled in blue in the picture
5) Now you should be able to wiggle the slide off the slide arm
Once everything is removed you should be ready to dip the carbs. By the way which carb body is it that is damaged? #1 has the choke lever on it and is on the left side of the bike when your sitting on the bike. 1,2,3,4
