Tonight I spent some time going through the new 80 getting it ready to turn over to my wifey. Put a new air filter in it, and couldn't believe how full the dust cup was. Amazing. Got me thinking that many of you may not even know you have this feature on your 80.
On the bottom of the air filter canister is a steel cup clamped on with a pair of spring clips like those holding your canister's lid down called a dust cup. It faces the engine, so it is impossible to see and the best way to find it is with your hands. One clip points roughly forward, the other roughly rearward. It is designed to help your air cleaner cope with larger particles by letting them fall through a slot as they enter the canister.
Once the dust cup is off, scrape out the crud with an old toothbrush, then bring it to the sink and gently scrub it out. Note that there is a hole in the bottom with a rubber membrane across it. This feature lets water out and does not work if allowed to crud up. Gently clean it with water and soap and then fill the cup with water and it will rinse itself clean as the water flows out into the sink.
When replacing it, note that there is a tab on the cup's lip that fits into a matching notch, which you'll feel with your hand. There, now you're ready for the dusty spring roads as the traction sand and salt dry and get kicked around the roads.
