Motorcycle Universal Manifold Vertical Motorcross Review

This so-called "Universal Manifold" was a hassle to install, and offered little to no performance benefits in my automotive application. Through trial and error, I found that the manifold actually impeded airflow and hindered engine power. The only positive was that it was made of durable material. On the downside, the design was completely inefficient and not worth the price tag. Save your money and invest in a better aftermarket part.

Had to drill a new one to install on my Kawk 250. Rubber razor edges to allow nuts to go further. It worked, but it certainly took some effort.

The adapter I received looked like it was cut for a utility knife and therefore had a taper in the hole where it attaches to the carburetor. As a result, the carburetor would not stay in the adapter no matter how tight the worm screw was.
