Random hole in my nc29 air box lid ?

Post by royster81 »

I need some advice guys, I have a random hole in the front of my air box lid beside the two rubber snorkels.
It's it meant to have a pipe/hose/grommet in it?
It's it meant to be left open to draw air?

What happens if it's blocked up?
It's not having what you want but wanting what you've got....Loud ,Proud and Modified ....

I’ve never had a standard nc29 with a standard air box but could it be for part 9 in this pic?

Yup thats the one, it doesn't go anywhere really, i cant see it having any major effect on the performance, looks like its called a sound duct for the JDM bikes so maybe something to do with noise tests in Japan? Thats a stab in the dark though

Its only a very short piece and the end that isn't in the air box doesn't attach to anything else so i wouldn't stress about it
