The '''Kawasaki G31M "Centurian"''' was a 100cc, [[Two stroke|2-stroke]], [[off-road motorcycle]] manufactured by [[Kawasaki]] from 1970 through 1971.
==History==
==History==
In the early 1970s the highly tuned '''G31M''' was a dominate force in [[Flat Track]], [[Tourist Trophy]] and some [[motocross]] racing along with its larger brother the 250cc [[Kawasaki F21M]]. This model consistently dominated the 100cc class with its unheard of 18.5 [[horsepower]] rated engine.  The small tip or "stinger" on the expansion chamber gave the Centurion a distinct sound that is unmistakable to this day. The engine case was slightly different than other Kawasakis with the G31M having a secondary air intake on the carburetor cover. It also required the use of [[bean oil]] as a fuel additive for lubrication.
