???Indian Scout 1920 engine sound

The Indian Scout is a motorcycle built by the Indian Motocycle Company from 1920 to 1949. Designed by Charles B. Franklin, the Scout was introduced in October 1919 as a 1920 model. The Scout had a sidevalve V-twin engine with its transmission bolted to the engine casing, allowing a geared primary drive - the only American v-twin to use this maintenance-free system. The Scout engine initially displaced 606 cc (37 cu in), but the engine size was increased to 745 cc (45 cu in) in 1927 in response to the popularity of the Excelsior Super X. In early 1928, a front brake was added to the Scout.
