I've restored at least half dozen sets of those Keihin's, during which time I learned a thing or two.
And speaking of that...be sure to inspect your float bowl overflow tubes carefully. They love to crack. It's not too hard to replace them so don't panic if they are. Also, be sure to remove the pilot screws; drill a hole in the cap and then thread in a screw which you can use as a lever to pull the cap out with Then make a small hook tool from a piece of wire and remove the spring, washer, and old o-ring before dipping the bodies to clean them.
I already removed all the plugs. They came out really easily. Should I remove the bleed pipes? They are underneath the primary main jets - I just can't see any screw driver slot. The one I messed up and had to drill out, I ended up kissing the top of the bleed pipe with the drill bit.
