Eccentric Engine Stud from CASA PERFORMANCE for Lambretta—creates additional space on the intake side for tuned cylinders with diaphragm valves.

The eccentric cones on the CASA PERFORMANCE engine stud offset the engine by a few millimeters. This creates additional space on the intake side of the cylinder. This is particularly helpful when installing tuned cylinders with diaphragm control.

A flattened side on the bolt and the cones prevents the components from twisting. The Engine Stud is designed as a Screw, meaning the hex head is permanently attached to one end of the Bolt. This allows the position of the cones to be readjusted even after installation, which significantly simplifies the installation process.
