Its the air filter housing. to remove it there are two allen bolts that you can see in the photo and three down the back which you will ideally need lonf "ball" ended allen keys. The three at the back can be awkward. The filter is inside.

Thanks for the reply I know it is a fliter housing but my question was. There is a hole in the side of the housing is it meant to be there?

Im not sure of its purpose, but mine has the same hole there.

The hole is for a plastic hose clip.

So should this hole be filled in???

I believe this hole is a drain hole for any water that gets into the air filter housing. It should be clear and unblocked.

It is a hole for a plastic clip to hold the extra pipework for those models with an FBH fitted

Just put that big, red arrow in it, that should sort it.

Ok but wouldn't a drain hole be underneath not half way up the air filter housing. Surely it should all be sealed?

Hey that arrow took bloody ages to create ha ha ha

it is for a clip to be there if water had got in and it was that high up in the filter box then the engine would be knackered

The hole as stated above is for a clip to carry wires within a sheath, but is used on the R75 M47 engine as below

Ours the FL as a different for holding the wiring sheath as here below.

Thanks for the replies I shall block this up then as there is no wiring nearby to clip in as I belive the extra wiring is for the fuel burning water heater?

My mistake, I should look at the picture closely before commenting next time. The small hole I was mistaking it for is right at the bottom of the housing. It does appear the hole you're worried about is just for a plastic clip as everyone else has said, and is absolutely nothing to worry about.
