Hi All,

Just trying to fine-tune the air/fuel setup of my recently restored '79 DT175MX which seems to be running slightly lean at higher revs/throttle position.

Looking at the top of the airbox/air inlet there is a circular hole there which Im not sure if it should be there.

Can I ask if any of the DT gurus here could clarify if its standard, or if a PO has taken a drill to it.

I realise it wouldn't make a great difference to A/F readings but it'd be handy to know.

Here's a pic, showing the "hole" in question, at the bottom, just before the connection to the airbox/filter housing.........

Many thanks Airhead! Much appreciated.

I know it won't resolve the slightly lean/hot running but good to know whats stock and what isn't.

I'll neatly tape it over with black gaffer tape.

What exactly is the contraption!?

Looks like its designed to make the air dizzy before it enters the filter box!..........

Cheers again Airhead!

can i just add something to this , i was wondering about that hole myself ! my airbox has one in exactly the same place but it has a piece of sticky oblong foam covering it ... that looked stock factory so i left it alone .
