Here is a DIY steel manifold that I bought for my Virago XV750.

As I mentioned earlier, the 2 carbs originally faced 180deg (opposing) each other. One connected directly to each cylinder.

Now, I use this steel manifold to place the single carb to the right side of the bike, near my right knee. Works very well using one of the two original Mikuni carburetors that came with the bike.

Note: Unlike the V-Twin Harley's, the Yamaha Virago V-Twin cylinders are offset. Front cylinder is offset to the right and rear cylinder is offset to the left side of the bike. That is why the dual-to-single manifold mod looks like it does with one tube longer than the other.

The very bottom manifold flange, in the picture below, connects to the single carburetor through a rubber carb boot. The left and right flanges connect to front and rear cylinder.
