A plurality of bolts 66 is provided and each of the bolts 66 is selectively extended through the mount 22 to engage the cylinder head 16 at predetermined points on the cylinder head 16. In this way the mount 22 is retained on the cylinder head 16. Each of the bolts 66 may engage the cylinder head 16 at locations where pre-existing bolts have been removed from the cylinder head 16. The bolts 66 are extended through each of the first apertures 40 and the second aperture 42 when the mount 22 is coupled to the Evolution engine 14. The bolts 66 are extended through each of the first apertures 40, the second aperture 42 and the third aperture 44 when the mount 22 is coupled to the Twin Cam engine 14.
A compression unit 68 is provided and the compression unit 68 is removably coupled to the mount 22. The compression unit 68 engages each of the intake valve 18 and the exhaust valve 20 when the compression unit 68 is coupled to the mount 22. Moreover, the compression unit 68 selectively compresses each of the intake valve 18 and the exhaust valve 20 thereby facilitating each of the intake valve 18 and the exhaust valve 20 to be serviced. Additionally, the compression unit 68 facilitates the intake valve 18 and the exhaust valve 20 to be serviced while the engine 14 is mounted in the motorcycle 12 and without removing the cylinder head 16 from the engine 14.
The compression unit 68 comprises a fourth plate 70 that has a first end 72, a second end 74 and a bottom surface 76. The fourth plate 70 is elongated between the first end 72 and the second end 74. The fourth plate 70 has a first bend 78 thereon to define a first end portion 80 of the fourth plate 70 forming an angle with a central portion 82 of the fourth plate 70. The first bend 78 is positioned closer to the first end 72 than the second end 74. The fourth plate 70 has a second bend 84 thereon to define a second end portion 86 of the fourth plate 70 forming an angle with the central portion 82. The second bend 84 is positioned closer to the second end 74 than the first end 72.
Each of the first end portion 80 and the second end portion 86 may have a length of approximately 4.1 cm. The central portion 82 may have a length of approximately 12.8 cm.

A rod 92 is provided that has a primary end 94, a secondary end 96 and an outer surface 98 extending therebetween. The rod 92 is elongated between the primary end 94 and the secondary end 96. Moreover, the outer surface 98 is bonded to the bottom surface 76 of the fourth plate 70 having the rod 92 being oriented perpendicular to a line extending through the first end 72 and the second end 74 of the fourth plate 70. Additionally, the rod 92 is centrally positioned between the first end 72 and the second end 74 and the plate is centrally positioned between the primary end 94 and the secondary end 96.
The outer surface 98 is threaded adjacent to the secondary end 96. The outer surface 98 has a plurality of intersecting sides 100 adjacent to the primary end 94 thereby facilitating the plurality of intersecting sides 100 to be engaged by a wrench. The rod 92 may have a length of approximately 25 cm. The intersecting sides 100 of the outer surface 98 may have a length of approximately 5 cm and the intersecting sides 100 of the outer surface 98 may be arranged to facilitate a ¾ inch wrench.
The rod 92 is extended through the fourth aperture 54 in the second plate 46 and the fifth aperture 64 in the third plate 56. Moreover, each of the intake valve 18 and the exhaust valve 20 is positioned in an associated one of the first slot 88 and the second slot 90. The rod 92 is selectively rotated to compress a selected one of the intake valve 18 and the exhaust valve 20 for service. A threaded nut 102 is provided in the threaded nut 102 threadably engages the secondary end 96 of the rod 92 when the rod 92 it is extended through the second plate 46 in the third plate 56 to retain the rod 92 in the mount 22.
In use, rocker boxes are removed from the cylinder heads 16 on the engine 14. A camshaft in the engine 14 is inhibited from rotating through any selected means. The mount 22 is attached to a selected one of the cylinder heads 16 using the bolts 66. The rod 92 is extended through each of the second plate 46 and the third plate 56 such that each of the first slot 88 and the second slot 90 engages the associated intake valve 18 and exhaust valve 20.
The rod 92 is selectively rotated to compress a valve spring on a selected one of the intake valve 18 and the exhaust valve 20. In this way the valve spring may be removed, replaced and otherwise serviced without removing the cylinder heads 16 from the engine 14. Additionally, the valve spring on each of the intake valve 18 in the exhaust valve 20 may be removed, replaced and otherwise serviced without removing the engine 14 from the motorcycle 12. In this way each of the mount 22 and the compression unit 68 reduces the amount of time required to remove, replace and otherwise service the valve springs on each of the intake valve 18 and the exhaust valve 20.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, system and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
