5 Mini Engine Kits That Run On Real Fuel – SlashGear

The motorcycle enthusiast in your life will appreciate the V-Twin gasoline motorcycle engine that sells for $899.99 with a black wood or silver metal base and $879.99 with a redwood base. The four-stroke engine has a displacement of 9 cubic centimeters and comes fully assembled. It includes a fuel tank, lines, and tank stand, as well as an air filter, battery, and wiring harness. The air-cooled engine has a power output of 0.8 ps, which equates to just under one horsepower, and runs at between 2,000 and 8,000 rpm. Spark plugs, copper exhaust tubing, and an electric drill starter attachment are included.

14 out of the 15 buyers who left reviews for this engine rated it five out of five stars, with the lone three-star review mentioning the use of rubber o-rings instead of metal piston rings and the lack of an electric starter. 

Even some reviewers who gave it five stars reported issues with the ignition components or mentioned having to make minor modifications, such as one who wrote that he “ported the exhaust ports … added an extra shim on heads … made custom engine mount with damping … [it’s] perfectly usable as standard but I like to modify … I can highly recommend this engine.”
