Airhead airbox cover plate

Has anyone made one of these covers and willing to share instructions?

Best,

Why the need for a central filter when the carbs are fed by pods?

Interesting ..........

That one is for the crankcase breather.

Just measure the back of your engine and fold accordingly. Use a thin gage of aluminum and don't crease the corner too sharply, or it will crack. If you can't bend it, your local sheet metal shop can do it.

Put the folded piece in place on the engine and traced the curve with a marker, then cut to fit.

Looks easy enough to do. Just don't ride it in bad weather. Pumping water and dirt thru these engines doesn't do them any good.

I'm not sure I follow you on this. Are you saying the cover would cause a problem or are you commenting on velocity stacks on the carbs?

I assume he is talking about the air filters.

I have set up more than a couple of crankcase breather setups and the setups I see above would cause a potentially dangerous oily mess in my experience. Those setups will very quickly have oil dripping all over the bike including your tires! At least if you rev them and ride them hard!

I have mentioned this fact before and some have claimed that it is not the case but I still don't see any photos of bikes with some miles on them. In my experience, they have to be positioned just so or speeds above about 90mph will have the slipstream wicking oil ALL over the back of the bike including the tires!

If I wasn't CAREFULLY running my vent out the back, I would have a catch tank but remember that even the catch tank has to be vented so keep an eye on that as well. That's my advise if you plan on riding the thing.

Do you think the cover would be water-tight?

I rigged a catch tank with a breather on mine. I'm going to modify it a bit more when I get around to it. I've ridden it hard and checked and only have a fine mist of oil in it.
