Detailed Summary
The video begins with the preparation of a standard bicycle for conversion into a motorized bike using a MOTAX Lampa gasoline engine kit. The first major step involves installing the sprocket wheel onto the rear axle. The narrator explains that the provided rubber spacers are very hard and must be cut in half to fit correctly on the inside of the axle. Once the sprocket is placed, the video details the crucial process of centering it. This is done by tightening the mounting screws incrementally while checking for wobble, ensuring the sprocket is perfectly aligned to prevent chain noise, premature wear, and jerky movement during operation. Next, the assembly requires modifying the bicycle chain. Since the new drive system needs a shorter chain, the narrator demonstrates a simple method to remove one link. This involves grinding the head of the chain pin, placing the chain over a nut, and punching the pin out. After shortening, the chain is reconnected, providing the correct tension for the specific bike model. A significant portion of the tutorial focuses on a common mistake made during initial assembly attempts: the mounting bolts for the engine bracket must be inserted into the bracket before the bracket is attached to the bicycle frame. The video emphasizes that once the bracket is mounted, these bolts become inaccessible from the sprocket side, making pre-installation mandatory for a successful build. With the chain and bracket prepared, the engine is mounted to the frame. The narrator shows how to secure the engine using four bolts, noting that some bolts are difficult to reach due to the tight space between the bracket and the sprocket. Tips are provided on using a hex key and pliers, or even shortening the hex key with a saw, to tighten these hard-to-reach fasteners. After mounting, the engine position is checked to ensure the rotation does not interfere with the bell or other frame components. The alignment is verified by checking the gaps between the sprocket and the frame, ensuring smooth operation without snapping or binding. The final phase of the assembly involves installing the control mechanisms on the handlebars. The original handles are removed to make room for the new accelerator handle, and the gear shifter is moved to the opposite side to avoid confusion. The accelerator handle is installed by drilling a small hole in the handlebar for a locking pin, ensuring the handle does not slip. The narrator demonstrates drilling a precise hole and greasing the mechanism for smooth operation. The throttle cable is then routed through the frame bracket and connected to the engine's throttle shaft, with the locking nut adjusted to provide the correct amount of play. Finally, the kill switch is wired using an extended acoustic cable, completing the electrical connections. The video concludes with a summary of the main procedures, confirming that the bike is now ready for testing.
