Two inches is a good bit. Are you going drag racing? Sunday night, I might be able to give you the answer to a one inch drop but I am not sure that you can just double that for two inches. Maybe the smart guys wills pipe up.
All this reading just to get to this?
Just kidding, thanks for trying. People can rag on Dunlops all they want but every one I have ever installed took very little to no weight (not that I have them on the XX).
Walking is good for you. If it were me, it would be in the parking garage. No sun, no rain, no bird poop, no strong gust of wind to knock it over, no dog lifting it's leg on it, no homeless guy from sitting on it, well I guess you get the point.
Do you have any photos? I would like to see both the header and can. I have Yosh slip-ons and like them but they are on the quite side. Not sure about the full system.
Just to replace the clutch fluid, there should not be any air in the system if the person has a clue what they are doing. Now if they are replacing the line, that is a different story.

If it is just the clip-ons that are at different heights, no big deal. If the forks are at different heights, I would go ahead and fix it. I'm guessing the the dealer didn't mess with the forks to change the oil.
Make the bike closer to the ground. Sorry, I couldn't help it. It does help if you are short or for drag racing. If you like the corners, you will drag things. You will have to drop the front also.
Pretty much the opposite for me (my other is a Wing though). About 1 1/2 hours on the Bird and it feels like someone is pushing a very large knife through my knees. So it different for different people.
