Spray a can full of carb cleaner into about 1/4 tank of fuel, let it run until it's warm. Do this 4 times and see if it make an improvement. Use the spray stuff, I find it works much better than the pour in stuff.
Left side of engine between the two engine covers. You'll need to remove the rearmost cover. It's covered by a square piece of rubber. Best get a new one for the cost of it. 2x6m allen bolts holding it in place. Careful not to strip out the bolt head, make sure your tool is well seated before attempting to turn.
Check your air intakes to make sure they are open and clean right to the carbs, also use oem filters. Maybe try taking a run without airfilters and see if that makes any difference. Maybe the computer?
Remove false tank cover, left side lower and upper faring, radio etc, and the inside faring. The rest can stay. Cables can be tied together to work them into place.
I think that's it.
