Claim:
1. A variable lift valve train comprising: a lever bar pivotably engaged between a spring-loaded valve and a stroke limiter; wherein the spring-loaded valve opens and closes with respect to a cylinder of a cylinder head; wherein the stroke limiter is able to move upwardly or downwardly in order to adjust an angular orientation of said lever bar; wherein the lever bar is under the influence of an overhead cam, which rotates in proportion to an engine RPM of said cylinder head; wherein adjustment of the stroke limiter adjusts a timing and lift of the spring-loaded valve with respect to the cylinder of the cylinder head; wherein the lever bar is pivotably attached to the stroke limiter; wherein the lever bar is further defined with a first lever end; wherein a pivot pin connects the lever bar to the stroke limiter at the first lever end; wherein the stroke limiter is further defined as a bar-shaped object that includes a bulbous top end; wherein the pivot pin attaches the lever bar to the stroke limiter at the bulbous top end; wherein the stroke limiter is generally vertically oriented with respect to the cylinder head; wherein the stroke limiter is also biased upwardly via a limiter spring; wherein the limiter spring is positioned between a limiter cavity and a limiter shoulder; wherein the limiter cavity is integrated into the construction of the cylinder head; wherein the stroke limiter is also further defined with a bottom distal end that optionally contacts with a stroke limiter cam.
