Been making these for my car for almost 10 years. I have used both Lexan and good old fashioned Home Depot plexi. Cut to size, add a bit of door "U" channel (bought a pile of it off of two junk yard 924's for $3) and drill for your mounting bolt.
Even if your carbs a balanced really well (no "pisst") they discolor pretty quickly. I have put 10k miles on my car since 1996 and have gone through 5 or 6 pairs. I have heard that a backfire can cause them to melt/catch fire, but I have never had any issues.
I think they look really cool - I just got lazy and put the aluminum ones back on after my last set started to stain. One thing - you absolutely have to put a rubber washer inbetween the cover and the steel washer/wing nuts - other wise they will break if you even slightly over tighten. I put small rubber fuel line over the mounting post inside the aircleaner so I knew when to stop - they flex alot.
hey, scott.
thanks for the feedback! i only use them at shine-and-shows or when i cruise the lakes & not for everyday. they can be coated (after paint if applicable) to make them more duarble against fuel/oil.
i started with home depot stock, but i couldn't get the edge polished... are yours? how did you do it? i completely agree with adding a spacer, my first set cracked too! i was going to add a nice piece if i sold them, understand too that the engraved channels eliminate some of that need.
i figured the (custom) engraving, polished edges and no running to the depot for blank stock and a band saw might interest some out there.
air-cooled-nut: they're strong. but like i said, i don't use them for much... and i fixed my backfire, so i guess i'm not entirely sure.
ian, i would have blanks on hand. i was even thinking about engraving some basic designs to have on hand, but i don't know about that yet. in any case, the blanks are technically available now.
thanks
