  • Lubrication system and method of lubricating an internal-combustion engine
    Patent number: 7028571
    Abstract: An apparatus and method for lubricating an internal-combustion engine includes a shaft extending through a gearbox, a gear and a sliding sleeve coupled to rotate with the shaft and adapted to move axially along the shaft, a gearshift fork in mating engagement with the sliding sleeve and moveable parallel to the shaft, a rib in the gearbox adjacent the shaft, and a duct extending into the gearbox. The duct preferably directs a lubricant onto the gearshift fork and the sliding sleeve. Preferably, the rib directs the lubricant from the duct onto the gearshift fork and the sliding sleeve. In an alternative embodiment, at least some of the lubricant flung from the shaft, gear, and sliding sleeve contacts the rib and is directed onto the sliding sleeve and the gearshift fork. Further preferably, a projection extends from the rib to direct the lubricant onto the sliding sleeve and the gearshift fork.

  • Apparatus for indicating oil temperature and oil level within an oil reservoir
    Publication number: 20060000103
    Abstract: A dipstick that measures and externally indicates the temperature and level of a fluid within a fluid reservoir. For example, in one embodiment the dipstick measures and externally indicates the oil temperature and oil level of oil within an oil reservoir of a motorcycle or other vehicle. The fluid temperature and level are indicated on an externally viewable portion of the dipstick, such as an exposed end or cap. The viewable portion indicates the fluid level when the fluid temperature is within guidelines recommended by the manufacturer or when the fluid temperature reaches a minimum threshold temperature.

  • Breather assembly for an internal combustion engine
    Publication number: 20060000458
    Abstract: A breather assembly for a motorcycle engine includes first and second substantially identical rocker supports that are each coupled to a respective cylinder head. Rocker covers are coupled to the rocker supports and cooperate therewith to define respective rocker chambers. Each rocker support defines a first breather passage and a second breather passage. A first breather assembly is coupled to the first breather passage of the first rocker support, and second breather assembly is coupled to the second breather passage of the second rocker support. A gasket member positioned between the rocker supports and the cylinder heads obstructs the unused breather passages of each rocker support. A sealing member is also provided that seals the interface between the rocker support and the rocker cover, and that also seals the interface between the breather assembly and the associated breather passage.
