ABSTRACT:
Preferably, a motorcycle valve spring removal tool includes a motorcycle engine operatively mounted and secured to a frame of a motorcycle, and a valve spring compression tool secured to the motorcycle engine for use in removing a valve spring of the motorcycle engine while the cylinder head remains torqued to the cylinder, and the motorcycle engine remains mounted and secured within the motorcycle frame. In a preferred embodiment, the valve spring compression tool includes a base plate supporting a stud reception member that provides a threaded stud attachment aperture, in which a corresponding threaded stud is secured. Also included in the preferred embodiment is a compression plate interacting with the threaded stud and a force transfer component, preferably a threaded nut, also interacting with the stud to impart a compression force on the valve spring to achieve a predetermined level of compression of the valve spring.
