I
have finally progressed to the point of mock-up of the
intake "plates" and mounting of the Holley
carburetor. If all goes well, placement of the nylon
adaptor plates and carburetor mounting plate will come
soon!
This is the
rear of the intake with plates attached. Instead of
having a carburetor mounted at each point, a straight
piece of PVC pipe will run to the stock aluminum
"elbow" and into the head. You will notice that
the perch for the accelerator wheel and choke are ground
off. I may end up grinding off the "foot" at
the bottom of the picture as well.
The Holley
2110 is almost a perfect fit into the stock air box
opening. A thicker piece of nylon will be cut and
utilized as a mounting plate between the carburetor and
intake.Stay tuned for more developments!

Second Mock- Up
Over a year
since suffering a brain cramp and coming up with this
weird and wonky thought about throwing out the metal and
embracing polyvinylchloride, the second mock-up is made
and ready for fitment!
Ain't she
pretty!!?? A mug only a mother could love, huh? The
original air box is the silver hunk surrounded by the
slabs of white stuff. The slabs are 1/2" nylon
"blocks" (similar to what cutting boards are
made of). The intake runners shooting off to the sides
are simple 1& 1/4" PVC pieces cut to 4 inch
lengths. The blue goo is good ol' RTV blue silicone
sealant. The challenge to making this thing, and keeping
it running is to turn an "everyday" (leaky) air
filter housing into an airtight assembly. Hence, the tube
of blue goo...
Side shot
giving a better view of the carburetor flange. The stock
air filter housing has two bolt holes sunk in at opposing
corners which normally hold the air filter assembly
together. After cutting the dimensions of the flange, a
good friend, Big Ed (and one HELLUVA Harley builder),
drilled a hole into each corner. He then countersunk two
bolts (the blue circular spots) into the stock bolt holes
and then double threaded two flange bolts on opposite
corners (bolts sticking up). The carburetor came with a
very heavy, cast iron intake flange, making fitment of
the carb to the nylon flange "do-able" with
only two bolts.
