hi everybody! i made this awesome model of a 1 cylinder dirt bike styled engine
and transmission. i wanted to make a functional model you can show off on your desk at your house or the office on the left side of the engine there is a disk with a hole you stick your finger into to turn, turning the disk turns the crank shaft and moves the piston up and down, and the crank shaft turns 3 gears that are linked to the transmission gears and finally rotating the sprocket, to liven up the design i made some cosmetic details like a timing chain cove and cam covers and an oil pan also a carberator, along with window on various parts to let you see whats going on when you crank it over! criticism is welcomed also any thoughts on a next model?
