Airhead racers SUMP windage trays and baffles INFO?

Anyone have info on those special windage trays and baffles used on some post 1970 airhead boxer twins racers crankcase and sump.I was told that the Buttler and Smith race bikes used them to control air and oil flow from the crankcase.

995 pan, cast in April 1983, from an R65. Cast with part number 1 336 994.
I don't know if this is what you are asking about, but this is lifted from Anton's page on oil pans and dipsticks, linky here.


Take a look at Anton's site, it may have the information that you are looking for.


And, as always, a big thanks to fellow-ADV'r Anton Largiader for sharing his website and knowledge with airheads everywhere...

Wow this is a good looking oil pan. I think it's a Falert made of magnesium should contain at least 4 liters.

A windage tray is usually a stamped piece of sheet metal that is mounted between the crank shaft and the oil pan. Baffles are raised sections inside the oil pan that limit oil sloshing within the sump wile chanelling the oil supply near the oil pick-up.

I use the same sump as pictured above..the one from Anton's site.
It has baffles but no windage.
I think you only really need the windage for sidecar use.

I have a sump extension, but not to increase oil volume, to increase crankcase volume for better crankcase breathing.

Here it is.
