Join me in this exciting video as I embark on a journey to upgrade and finetune my HiSun engine using a Mikuni VM22 carburetor clone. I'll share my experience—from unboxing the carburetor kit to finding the perfect carb needle height for optimal performance. Watch as I figure out how to remove the stock carburetor, install the new VM22, and test ride the bike with various adjustments to achieve the perfect balance between fuel and air.

Key moments in the video include:

Unboxing the Mikuni VM22 carburetor clone and exploring its components
Comparing the stock HiSun engine carburetor with the VM22
Figuring out how to install a new throttle control and instrument panel
Navigating the process of removing the old carburetor and installing the VM22

Understanding the importance of fuel line clamps and securing the gas tank
Assembling and installing the new throttle kit
Overcoming challenges with the throttle control and making necessary modifications
Multiple test rides to finetune the carburetor for optimal performance

Throughout the video, join me on four test rides as I experiment with adjusting the carburetor for the ideal fuel and air mixture. I'll discuss the challenges of running too rich or too lean and how I learned to adjust the needle height and jet size to achieve the perfect balance for my bike. By the end of this video, you'll have an inside look at my experience upgrading my HiSun engine with a Mikuni VM22 carburetor clone and the resulting improvement in its overall performance.
