AWESOME Scale Model Harley Engine That WORKS!!!

Article Written by : Legendary Videos

This engine was built from the ground up for a 40% scale of the real thing. The bottom end was taken from a drawing of a Knuckel head engine that the designer had bought from internet. The top end was designed by looking at photos of actual Harley parts. This engine is just barely large enough to create that unique and awesome V-Twin sound. I love this thing!

That was nuts. Wait until you see the next video below.
