Air Cleaner Drain

[xszgrider]

My air cleaner housing appears to have some sort of drain. This drain hole is always open (appox. 1/4" diameter) allowing unfiltered air into the carburetors.

Is this normal or is there suppose to be a plug in there?

Thanks

There is supposed to be a plastic piece there that holds a small foam filter. This piece snaps on to the air box. You can get one from Bikebandit.com, P/N 22591-001, $6.59 ea.

The drain is located on the inside of the filter element, which is the dirty side. Any air that would enter the drain will be filtered before it goes to the carbs.

That's not entirely true ken. The drain is in the 'clean' area of the airbox. It is located in front of the filter, hence the foam material that should be in there.

Oops - John is of course correct. The airbox drain is in fact on what is supposed to the clean side. My bad...

foam material

Apparently, my air filter housing was missing the foam. I cut a piece of air cleaner foam, oiled it , popped the cover off, and installed the foam.

Hope that works.

I use a bit of metal screen material between the inside of the air box and the foam. It will keep the foam from being sucked into the airbox when it gets dirty, and keep any flash fires from escaping the box in case of backfires. Just cut it to fit the square hole for the filter, and then install the filter and plastic keeper. The OEM material was a square of sintered bronze. (sp?)

Metal Screen

Ray,

Thanks for the info. I thought about putting in a metal screen but didn't see any screen handy. There is probably something here I can use. I have a lot junk including radio parts.

Thanks,

John
