Hi. As above,and also what it's  purpose?. Does it lesson oil, getting flung into the the breather arrangement?.

Thanks Dave

this is generally a metal gauze  bit like a pot scourer , might be plastic as metal ones could vibrate and break up.

it purpose is a flame trap to stop( like a davey lamp) any cross fire between engine fumes and carburation 

just prise the surround open remove and wash in petrol or a cleaner then replace 

if you fit an alloy cover these dont have this and really should have a remote flame trap in the breather hose 

as many makers use like this

My rocker cover doesn't have a gauze, instead an arrangement of interleaved plates. I went on the interweb to find a diagram but could only come up with this link to a little known forum, some interesting exchanges including some one called daveclasper, any relation?

Some covrs do, some don't, nonidea of the logic.    The pot scourer inside is often clogged with black gunge, best levered out and thrown away.  Replace with wire wool if you must.
