If you have the kit, you might as well used the block off bolts for the head. The injectors in the head need to be blocked off properly so the head is sealed up tight. I bought my bike used, with the injector bolts plugged with some misc bolts. Which in time loosened up and fell out while i was riding. Talk about loud
besides with the injectors out of the way you can change the spark plugs alot easier which would help out with the laziness you obviously suffer with..haha
Like i mentioned my AI was already removed so Ive never done the job myself, but Im pretty sure you can leave everything on the bike as long as everythings plugged up on both sides (head, carbs etc)...with the AI removal kit.
Honestly you should suck it up and remove the tank and the seat. Theyre both an easy job and not really that time consuming. I myself am just like you, I'd rather change the things out without disturbing anything else. I hacked my airbox with a sawzaw while it was still on the bike.
All that mentality does is make you work in less than pefect conditions. Without the proper clearance to turn wrenches youre just gonna add more time and aggrevation to the project than you would if you removed the proper pieces and did the job right the first time.
You should be thanking god that you have one of the last modern motorcycles that will allow you to work on it yourself. The newer models coming out will be alot more complicated for the average joe to work on and pretty soon we'll all get emails from our bikes for when its time to take it to the dealer and pay them to remove 45 pieces in order to change the left blinker light bulb.
