Just type - 1915 Excelsior - and look for the old man. He looks like he is about 65 or 70 years old. This guy scratch builds a 1915 Excelsior/Indian single cylinder motorcycle - engine frame and even the headlight ( gas light head light ) !
In another video - hear it run ! ! ! It sounds like someone has a hammer in each hand - pounding away on the bottom of a 55 gallon steel barrel ! ! ! Open header - big cubic inch thumper single cylinder - open rocker box - push rod over head valve. The timing and the carb sounds a little off to me - but they didn't have much for those things back in 15.
