I just spent three days installing the tunnel from the front of the lower cowling back to within 1/4" of the air box per Vans instructions. I put two washers under the front two mount plate to carb bolts to lower the air box during cowl tunnel install per Vans instructions to allow for future engine sag. After finishing, I am wondering if this was a good idea. Looks like I have about 1/4" vertical difference between the tunnel and the air box inlet. Now I am wondering how the black baffle fabric will seal this. I can rivet the bottom "U" shaped piece to the air box and I suppose it will seal okay, but the separate top piece would be just hanging up their with no forceful seal, 1/4" above the top of the tunnel. Now I am wondering if I should have ignored Vans suggestion to build for future engine sag. Comments, suggestions, pictures appreciated.
Here is a close-up photo of the carb air inlet showing the "sag" gap:
