IF YOU HAVN'T DECIDED YET....
I had a problem on my arlen ness BIG SUCK where the alum. back plate DID break=out on the bottom two bolt to carb.... I do believe it to be a DESIGN FLAW in their casting process; NOT thick enough where the inverted bolts go thru the alum. back plate to carb... breaking-off leaving alum. thinner than washers behind the bolt.. IT WOULD HELP THERE TO BE TWICE THE THICKNESS....
I did buy another full unit, a n big suck as I had the old one for about a year and JUST WANTED IT FIXED TO RIDE... an NOT hassle or BE hassled trying to get it on a WARRANTY issue...
Looking at the new one it is about as thick(i should say THIN) as the old one.(broken)
I probably will be okay on the re-install of THAT SAME part as I don't put the miles on my 06 SPORT 1200 R AS I used too, it was my main bike while down in AZ. a few years back and I put 34,000 miles on it there...
I went with S.E. AIR from harley. HAPPY WITH IT and use the stock outside football cover.. on my 09 FLHR.....
I did see a nice ROUND harley AIR cover for 59$ at the HD shop.
I used the ROUND cover from NESS on the sport, NO markings on it, JUST plain chrome, IT does LOOK GOOD.
Just thought i would add the breakage of NESS here on this thread as i think people NEED to be aware of the problem..
