Howdy,
Here is my beefy Filter Air Box (FAB) rebuild. At 600 hours I had cracks in the 0.0625 alum FAB plate, the door hinge was disintegrating, the cable attach lever hole was totally moofed. I know others have had similar issues with vibration in this assembly.
I used 0.125 alum plate with a 0.125 doubler/washer plate. Note the aluminum angle spanning the entire width of the FAB plate to stiffen the whole assembly. Note also the 0.125 angle brackets for the SCAT tubing flange mount. The door hinge is now baffle material sandwiched between (2) 0.040 plates - it seals MUCH better now as indicated by improved RPM drop at run-up carb heat test. Instead of the stock cable end bug thingy, the cable is now attached with a rod end for less shaky.
Seems to be holding together well so far!
Cheers!
