The intake snorkel parts are from
http://siliconeintakes.com/4 x Stainless Steel 2.5" Worm Gear Clamp (46-70mm) (CLA001042) = $5.96
2 x Stainless Steel Joiner, 2.5" (JOI000112) = $15.98
1 x 2.5" Silicone 90° Elbow, Black (SIL000033) = $16.99
1 x 2.5" Silicone 135° Elbow, Black (SIL000664) = $29.99
The 135 degree elbow is cut way down and fits to the carburetor. The SS joiners are carefully scalloped so that the inside of the intake path is smooth. This is where most of the work is.
The petcock is so close to the intake snorkel that it presses against it and indents it slightly. This is why the OEM petcock has to be replaced because it's too big. I cut away some of the SS joiner to make this area soft so it could press in slightly to accommodate this interference.
The air filter is from K&N and is part number RA067V $45
It has an offset intake and that's critical in the fit-up.

It's turned on and off from the right side and the fuel nipple points down on the left side. The rotation of the petcock is about 15-25 degrees off-normal. You can't tell this when using it and the rotation avoids some of the interference.
