Intake D port floor installation

Temporarily install the teflon gasket and make a mark aligned with the valve guide.

 

Place a small dab of silicone gasket sealer or “The right stuff” at both ends of the port floor and tilt it into place. Make sure the gasket is correctly located and does not slip out of place when tightening the manifold bolts. Sealer is not needed on the gasket.

 

Race and hot street bikes should streamline and port approx 1mm wider and higher around each side of the guide similar to the cobrahead shape shown below.
