Right side of handlebar showing brake lever (outer lever), throttle (inner lever made from BMX brake lever), and the engine cutoff switch. The engine can be easily started while you're riding. No need to stop. Just reach behind, adjust the choke and prime by pumping the primer bulb if cold, then pull. Two pulls for a cold start, one when warm. I plan to make a new seat cover for the torn front seat shown in this picture.
