  It's encouraging to see that there's manufacturers making parts to adapt low cost air cooled engines for use in experimental aircraft

  Hi, I built an airbike with this engine. There is some low cost intake and exhaust wizardry you can do to gain a lot of power on it. <br>The exhaust primaries must be 57 inches, and merge into a colletor, before the muffler. You can put it longitudinally below the engine.<br>The intake runners must be 10 inches each, joining into a 0.350 cubic feet plenum, and the you use a single honda NX400 carburetor into that plenum.<br>That carb is great because it has a diafragm similar to the rotax 912, that gives altitude compensation.<br>PS: I understand the 10 inches of intake runner may be too long to be pratical in some cases, so you can do it with 5 inches. You will loose power but it still way better that original.

  On my VW dune buggies that were straight pipes I would cut the pipe in what was called a slash cut Not a 90degree cut. &nbsp;Then lightly hammer close the slash cut to change the open circle of the pipe to a long oval cut . This produces a very slight back pressure and a sound reduction. The slash cut should make the original 90 degree opening into to a 125% of the original opening ( which is only 25% larger than the original 90 degree cut). It will help with the Db level with no HP losses..
