  • Great Engine For the Price
Size: Auto Engine Motor 110cc 4-Stroke
Engine ran great definately an improvement from the 50cc I had. Came in a thick cardboard box with thick foam insulating it. All ports were coverd to ensure nothing got into the cylinder head. Paired it with a 19mm Nibbi carb and it had really clean operation. Electric start fires it up right away. Did come with a 428 front sprocket which I changed out for a 420 sprocket. Also does not come with oil. I used Valvoline Racing 4T 10W40 oil ... show more
