Haven't seen any directions yet. I had never seen this set up before.
For anyone who hasn't seen it, here's some info...(about 800 bucks)

Here's what they say about it...
"The Intimidator-
The completely re-designed dual carb plenum manifold kit from Küryakyn has been "under the microscope" and on the Dyno for the last two years. All facets of this awesome setup from the mounting hardware to the plenum's interior design have seen major evolutionary changes. The results are as extraordinary as it's fierce appearance.
Installation has been simplified drastically. The new one-piece plenum chamber, and redesigned intake connections create a hi-integrity seal and reduce the number of components involved.
This revised system also offers more flexibility as far as the choice of carburetors. For mild performance or stock applications, the use of two stock H-D constant velocity carbs is still recommended. But when an all out performance system is desired, more impressive results were attained by using a HSR42 Mikuni on the primary (right) side and a CV carb on the secondary (left) side.
How impressive?
One of this country's top engine builders and tuners, Vern Ott (of VMO) attained these results: Using a stock engine from a 1998 Electra Glide, outfitted only with a Crane HI-4 ignition, and dual Supertrapp pipes, a baseline of 67 Ft./Lbs of torque and 56.7 H.P. was established. Adding a .500 lift cam from former drag racing great Dave Mackie and the dual carb setup using one CV and one HSR 42 Mikuni, peak torque and horsepower jumped to 71.4 and 72.5 respectively*. Add to this the mental horsepower of the incredible looks and sound of a dual carbed and Hypercharged Big Twin, and you'll have a scooter that goes as well as it shows.
The Intimidator dual carb plenum manifold kit will fit Harley-Davidson 80" Evolution Big Twins as well as 96" and 113" S&S motors. Because of substantially longer or shorter cylinder lengths, the intimidator manifold will not fit other stroker or big bore engines."
