Thanks aerohead.
I like the basic concept - do the best you can and don't fall into the trap of fretting that it's not ideal.
Anyway, since a pic is worth a thousand words, here's what Sven looks like back there. You see the bumper, then a valence panel, then the muffler. Tank is at far right photo edge.
I think I may just run the screening material over the whole area. Screening to be painted so it becomes more of a solid sheet. I'll likely not paint directly below the muffler.
Any comments on heat buildup or anything else?
