RETROL R33 Evolution 4.2CC Mini V2 Engine OHV V-Twin Motorcycle Engine Double-cylinder Four-stroke Gasoline Engine Internal Combustion Engine Model

As a miniature gasoline engine model designed based on the V-twin Evolution engine of the 1970s motorcycle, this engine model embodies the spirit of different eras in a wonderful way.

Features a retro flavor, classic body lines, cold cooling structure, new carburetor design, and a push-type throttle lever, this most intricate engine model highly restores the details of a real engine. Upgrade the intake and exhaust valves to large and small valves, thus the power is significantly improved.

Each elaborate part in a fine process is made of brass and stainless steel materials, in conjunction with a wooden base for easy placement and operation, ensuring smooth operation.

Including starting and ignition devices, ready to run at any time, this model is friendly to novice model enthusiasts. You will be amazed by its good performance when it is running.

Perfect as a coveted collectible for displaying and playing with, as well as for personal use or as a high-end model gift for friends and family during major holidays.

  • Warm Tips:
  • 1. In the ignition device, if the machine does not start with the normal compression of the cylinder,  you need to adjust the needle of the carburetor.
  • 2. Tighten the main needle on the carburetor, loosen the one-quarter cycle, and turn the flywheel to ensure the mixture ratio of gasoline and air reaches normal.
  • 3. Turn off the power switch when the machine stopped.

    I bought this engine because it is a replica of the evolution engine in my 94 Harley Softail. When I first got it out of the box I couldn't believe the exact details and how much it looks like the real evo engine. It didn't take long to get it running and it sounds really cool. I have it on display with my other Harley collectibles.
