in stock. the order will be sent out within 1 working day.
Features:
.Based on the V-twin double-cylinder Knucklehead motorcycle engine in the 1970s, the miniature gasoline mini knuckle head engine model embodies the spirit of different ages in a wonderful way.
.Designed with classic body lines and cold-cooling structure, the retro machine restores a host of authentic engine details, including a new carburetor and lift throttle.
.Each part of the engine was carefully designed, processed as well as made of brass and stainless steel, working in conjunction with a wooden base for easy display&control and stable operation.
.Built with start and ignition equipment, the engine is ready to run and friendly to novice model enthusiasts. When running, you will satisfy and marvel at its operation.
.As a coveted collection, the engine model is worth showing and playing, suitable for personal use and a high-end gift to friends and families at major festivals.
.Notes: 1. If the engine is failure to start normally under the normal ignition and cylinder compression, it is likely that the carburetor needle will need to be adjusted.
2. After tightening the main oil needle on the carburetor, loosen 1/4 turn and start the flywheel to make the mixture ratio of gasoline and air reach the normal working mixture ratio after several times.
3. Turn off the power switch when the machine stops.

Authentic feedback from hobbyists, machinists, and scale model engineers
This little engine is great in detail and manufacturing quailty !
it was purchased as a gift to my best friend.
The engine started with very little adjustments needed to the carburetor. Fun to play with. It worked better using the pull rope to start it than the adapter with a cordless drill. Detail on motor is incredible.
It is a very nice recreation of the iconic Knucklehead V-Twin Harley Davidson engine. I have started it about 40 times so far and have found it quite reliable and easy to start by hand with a simple twist of the flywheel between my thumb and forefinger.
