   Many riders also fit aftermarket chain-oilers to feed a regular supply of oil to the chain at the rear sprocket. [8] These chain oilers vary in sophistication, but all add significantly to the life of the chain. The custom of lubing by immersing the chain in a tin of hot grease ceased in the early 1970s, once most chains had rubber "O'-rings.

   A driving factor behind the BSA/Triumph change was that Lucas [1] had declared an intention to abandon production of motorcycle dynamos and magnetos, and instead produce only alternators. By contrast, Velocette, Matchless/AJS, and Norton motorcycles continued to be pre-unit construction (the former machines with pressed-steel primary cases ...

   Breakdown of VIIs under shear is a concern in motorcycle applications, where the transmission may share lubricating oil with the motor. For this reason, motorcycle-specific oil is sometimes recommended. [18] The necessity of higher-priced motorcycle-specific oil has also been challenged by at least one consumer organization. [19]

   After they made further improvements to the oil impregnation and sintering technologies, they received a patent for their lube-free roller chain, as evidenced by Patent #JP20070237969. [5] In the new design, advancements in powder metal bush technology allowed engineers to design a bush that had a smaller diameter yet was stronger, which ...

   A sample of synthetic motor oil Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks .

   Belt drive was added to their motorcycles in 1980 to prevent the oil leakage from the enclosed chain, along with a 5-speed transmission and rubber motor mounts to help reduce vibration. [1] In 1981, Harley Davidson purchased AMF's share of the company back, adding a new oil pump, improved valve guides, and lowering the compression to help the ...
