New KZ440 Owner, with questions of course...

Hello all. I picked up a pieced together 440, built mostly from 80 parts with an 81 engine. I rode it home (probably not the best idea) and now I'm trying to get her tuned up. The first thing I did was replace and re-route the throttle cable since it revved up every time I turned the handle bars. The second thing I've done is ordered new carb holders because the ones on there are cracking. She starts up and runs, but idles really high/erratically. It will sort of rev up on its own and if I even try to push the choke down she redlines. It has pod filters (I know) but that's what's on there so I'm going to try and make them work. The carb has supposedly been rejetted two sizes up, the guy told me 1 for altitude (denver) and 1 for the pods. Here's what I started on today:

Change oil
Change plugs
Adjusted points
Adjusted valves
It looks like I have an automatic cam chain tensioner so I didn't mess with that.

I have worked on a lot of cars but never a motorcycle. Where do I go from here? I've been reading and it looks like I should check float level and sync the carbs. Are these things I can even do with a potential vacuum leak in the carb holder? Is there a good how-to on what things to look at on carbs and in what order? Also, the breather on the top of the motor is just open with nothing on it, i'm assuming I should attach a small hose and a filter to it? Sorry for the long post, I'll get some pictures of this beast up once I get her back together.

Here's a PDF of the shop manual.

This is from the KZ400 Web site, which is of course mostly about 400's. But there is a lot of useful material for the 440 there.

never mind

So here are some pictures of this beast (I didn't do the paint job and it's done with hobby paint).
To add to the above list I
-changed out carb holders and air pods/boots
-cleaned carbs, got new float bowls (overflow pipes were cracked), adjusted the float level, synched carbs and dialed in idle speed/mixture

I guess I'm not sure what everyone's trouble is with pods. She runs fine (I mentioned the PO rejetted), idles fine and has no throttle issues.
