Yamaha YA6 1966 USA information

Autolube used on two commercially available motorcycle models, the 75 cc YG1D and the 125 cc YA6. Autolube, was a breakthrough technological innovation for 2-stroke engines
(April 1964). Although Autolube was first used commercially in 1964, the 75 cc YG1D and the 125 cc YA6, the technology was first developed at the track for Yamaha's racing machines. Separate lubrication was used for a motorcycle raced in the France GP in 1961, providing a clear example of Yamaha's history of developing technology through racing.

* Yamaha unveiled its automatic lubrication system (Autolube) at the 10th All Japan Motor Show, the forerunner of the Tokyo Motor Show, in Autumn 1963.
* "Autolube," a combination of two English words "automatic lubrication," was revolutionary for eliminating the system for supplying a gas and oil mixture to the engine, which had been a weak point of 2-stroke engines, and replacing it with a separate oil injection mechanism. Like 4-stroke engines, the oil and gas could now be supplied separately. The debut of Autolube freed riders from supplying the mixed fuel themselves, curbed oil consumption, and substantially reduced exhaust fumes.
