I am a Harley builder and love this motor.
What an outstanding miniature engine!
I ordered my R29 Knucklehead immediately after it went on sale, and was thrilled when I got my notification that it had shipped from Stirlingkit!
This is my 5th engine that I have bought from Stirlingkit, and always look forward to what they will be releasing next.
My R29 arrived three days after it left Stirlingkit‘s warehouse, using DHL express shipping.
It arrived safely and in perfect condition, as all my engines and parts have arrived.
Stirlingkit‘s packaging method is outstanding, and the special presentation box they had made for the Knucklehead, really stands out and was totally worth waiting for. It’s a beautiful sturdy black box, with a picture of the engine embossed on the top section with the new Retrol brand logo.
The instruction manual that comes with the R29 Knucklehead contains a lot of engine information; such as specifications, setup & how to operate the engine.
The engine is completely ready to run. Install 3 AA batteries and add fuel.
For fuel, I chose ethanol free w’ added 2 stroke oil as recommended. I wanted to try starting my engine directly out of the box, using the preset carburetor setting.
My R29 started immediately using the included drill adapter, and idled perfectly stable.
This engine sounds incredible!
It has a very crisp exhaust note, and runs all through the RPM range beautifully. Although the fuel tank is small, it will run a surprisingly long time off a single tank of fuel.
The details of the R29 engine are spectacular. Retrol has put a lot of effort into even the smallest details, such as the tiny hardware, simulated oil pump & top-end oiler line, and beautiful CNC made jugs & heads.
I have now ran around 10 full tanks of fuel through my R29, and the engine continues to run better and better with each tank.
What I was most impressed with was the ease of starting. No need to use the drill starter after the engine gets a little time on it, one or two flips of the flywheel is all it takes to bring the engine to life now.
Stirlingkit has released yet another miniature scale engine to be extremely proud of, and the R29 will be another engine loved by their customers. Huge applause Stirlingkit 💕👏
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.
