.@CROSSBOLT, txs alot
@MOUSEJUNKS, txs too, didnt know there were two versions,
EDIT:
since I do no offroad or have dusty conditions it became CROSSBOLTs version.
On my scoot was already minimal configuration, filterwise, just a very thin layer of foam, not worth to be called filter.
Decided for version "minimal minus 1":
-cutted this basketlike part off (red circle)
-cut a fiberglass mesh into shape
-hotglued it in this frame (pls see pics)
Made a 3D scan before cutting, if I really need this protruding part, I might start the 3D printer.
