Join Tony from BikeBerry in the third installment of our Porting Masterclass series, where we delve into the process of decking a 2-stroke cylinder. This video is an essential guide for anyone looking to enhance their motorized bicycle's engine performance through increased compression and smoother operation.

Tony begins by explaining the concept of decking, which involves lowering the top of the cylinder by 1mm. This modification leads to more compression, smoother running, and reduced four-stroking. However, he cautions about the potential for detonation and recommends using higher octane fuel as a precaution.

The video provides a step-by-step guide on how to accurately measure and remove 1mm from the cylinder using calipers and a sanding disc. Tony emphasizes the importance of keeping the cylinder flat and even during the sanding process. He demonstrates how to use a blue fine tip permanent marker to make guiding marks on the cylinder corners, ensuring even sanding and depth.

As the process continues, Tony shows how to check the evenness of the cylinder head using calipers and how to measure the depth around the parameter. The final step involves polishing the cylinder on a glass table with fine grit sandpaper, ensuring a perfectly flat and smooth finish.

Tony concludes the video by reiterating the importance of precision in this process and encourages viewers to try it out themselves. He also teases the continuation of the porting and modifying series for motorized bike engines.
