OK, now I'm not on my mobile, and can see what I'm typing, answers to a few questions;
Technique for applying, I used a single piece for each side, started in the middle and worked out. I think it would be impossible to do without a heat gun, I used it constantly - heat / squeegee let it cool and it stays where you put it.
The vinyl itself seems happy to be stuck / peeled / restuck / heated / cooled indefinitely without losing it's stickiness. It leaves no residue while you;re doing that, which I think probably answers the question as to how easy it is to remove. I'm guessing it's very easy, it's strong stuff, it will definitely peel off in one piece.
Air bubbles - I avoided them mainly by reapplying several times till I got it right, but close up there are a few small ones (1-2mm) still in mine. I pushed them to where the decal is, so they're not obvious. Same goes for ruffled edges, there are a couple on mine.
Basically if you stand up close and really look carefully, it's far from perfect, but out and about it looks great. It may be that because my technique involved a lot of heating / stretching, over time the stuff will try to shrink back to its normal shape and it'll look rubbish, but if that happens I can just peel it off and do it again, hopefully better . . .
On Da1kinis carbon fiber wrapped mirrors, firstly I'll say what a great job you did, looks great. One thing I'd say about doing carbon on the tank - as it's a bigger and fairly complex shaped area, I'd imagine you'd have to be really good at it to do it in one piece and not distort the carbon pattern.
But overall, it's easily doable in half a day, including getting the panels off and back on. As Spartan 72 said, you can pretty much change the colour on a whim, it's cheap to do and if you look on Ebay / Amazon etc there are just endless different things you could do. I'm thinking when I get bored with that to do a multilayered Union Jack scheme. It's probably easier to do, as you can do it in sections.
Legality - it did occur to me that the V5 is now incorrect, and I'm not sure how big a deal that is, but my view is that on any given day it's unlikely to be the most illegal thing I'll do on my bike so I'll live with it
