Anyone have an idea of how to make something like these?
Turn them up on a lathe (Jean, are you busy?) and fit some mesh. Maybe o-rings or something to retain them?

Mesh are from a fifties Blaupunkt radio by the way.

Dave, those wouldn't be too hard to make, but I wonder if they would provide enough ventilation.

I wouldn't run a hole saw, much better to put them in a lathe, no?
Please forgive the interuption of the topic but what is the thing between the motor and the airfilter? FI?Jeandr said:

So, back to the subject. Jean, should I send you my inspection caps so you can core them out. Have just the threaded rings would be better than just the holes. Not sure how to do the mesh yet. What are those caps made from? Aluminum? Or cast dog shite like the Amals?
I have seen covers with the forward facing portion of the raised areas cut out with screening imbedded. I keep my eyes out for it. An area behind the clutch for exhaust would be good to.chris plant said:hi all,those primary covers look "cool" but there not really,a properly vented primary would need entry holes or a scoop at the front and exit holes at the back,something like you would do with a drum front brake
