Late airhead air injection.

[Jon T]

Evening all.

I’m off to look at a very late R100RT Mono in the morning. It seems to have additional pipes from the air box to the head. I seem to remember something about an air injection system to improve emissions - was that a thing? Does it cause any trouble, or does it just work? Any pointers gratefully received, ta!

yeah just blank it off It will be okay

an Oil drain plug fits

I will try and find which one

..or you could leave it in place; they don't cause much agro. Having said that, I removed mine but as well as the blank referred to above, you may need to cover up the holes in the airbox as they look unsightly to some. I got hold of a pre-mod airbox with no holes.

As above, leave as is, But if those pipes are hot all the time something is not right

07119902292 M16X1,5 I believe is the correct plug that works and you can get stainless ones too

Maybe a couple of second hand ones AND of course be careful inserting

Or I have seen tricks with a ball bearing / stainless disc plugging the end and refitting pipes and the crap inside the airbox thrown away Keeping the original looks

I have a 1994 R100RT Classic on a N registration. It has the pipes as you describe. Never had any problems with the bike and I've done 6K miles in the last year ( 2 European trips) I'm leaving mine on.
