Open up the big glove box, and inside, up in the centre of the roof is one of those pesky plastic clips.
On mine it's different to all the other similar clips that are all over the bodywork, in that instead of having a centre push button, it has a cross head screw. If you turn it 1/4 of a turn, you can then lever it out, but it's fiddly.
Then pull the small central panel above the glove box (under the handlebars) back towards you, it has two internal friction clips but they just pop out.
The radiator pressure cap, and the plastic header bottle cap are right there. The daft thing is, my rider's manual says check this before each ride!!! I'm sure they're just covering themselves.
I don't think it really needs the first little clip as the two internal ones are quite strong.
