English questions :)

Hello, everybody!
Sorry for english, but my german knowledge includes very few words %)

This is a very useful forum, it's a pity I cannot understand most of it.
Just to summarize and check if I understood correctly I want to ask some questions. I'm sure you've answered them many times, and I beg you pardon But I shoud know 100% before rebuilding or buying something.
So, here they are: )
If I put a rim from zzr1100 into original swingarm, will the 180mm tire fit in?
What is the easiest option for upgrading swingarm (the one from zz1100 also, if i'm not mistaken)? In a few words what types of mods are required for different possible swingarms?
Same question for the forks - forks from what models will fit into gpz's frame whithout (or little) modification?
And a little different subject, but I don't want to multiply topics. Does anybody know the standard settings for gpz750r's carburetor's "fuel-air mixture screw" (the one in the front-bottom on each carb). I know that for gpz900 it's 2.5 turns out, but not sure it's the same for mine.
Thank for any kind of help in advance!
Good luck!
Alex.
