023 USVH radiation is not inherently dangerous as it falls within the non-ionizing radiation spectrum. Non-ionizing radiation, such as radio waves and microwaves, does not have enough energy to remove electrons from atoms or molecules, which is what makes ionizing radiation harmful. However, prolonged exposure to any form of radiation, including non-ionizing radiation, can potentially have negative health effects. It is always recommended to limit exposure to any type of radiation to minimize potential risks. **

A kickstart crankshaft is designed to be manually started by using a kick lever, requiring physical effort from the rider to start the engine. On the other hand, an electric start crankshaft is equipped with an electric starter motor that allows the rider to start the engine with the push of a button, without the need for physical exertion. Electric start crankshafts are typically found on more modern motorcycles, offering convenience and ease of use compared to kickstart crankshafts. **

The crankshaft can be filed by using a precision file to remove any burrs, nicks, or imperfections on the surface. It is important to use a file that is specifically designed for metalworking and to work carefully and methodically to avoid damaging the crankshaft. The filing process should be done with the crankshaft securely held in place to prevent any movement or flexing. After filing, the crankshaft should be thoroughly cleaned and inspected to ensure that the filing has achieved the desired result. **

The crankshaft slides horizontally through the use of bearings and lubrication. The bearings are placed at specific points along the crankshaft to reduce friction and allow for smooth horizontal movement. Additionally, lubrication is applied to the bearings to further reduce friction and ensure the crankshaft can slide easily. This horizontal movement is essential for the crankshaft to transfer the up-and-down motion of the pistons into rotational motion. **

The original crankshaft may or may not be able to handle it, depending on the specific circumstances. Factors such as the engine's power output, the type of modifications being made, and the condition of the original crankshaft will all play a role in determining whether it can handle the changes. It's important to consult with a knowledgeable mechanic or engineer to assess the crankshaft's capabilities and determine if any upgrades or replacements are necessary. **

Crankshaft threads can be re-cut by using a thread chaser or a tap and die set. First, the damaged threads need to be cleaned and prepped to ensure a smooth re-cut. Then, the thread chaser or tap and die set can be used to carefully re-cut the threads, following the original thread pattern. It's important to use the correct size and pitch of the thread chaser or tap and die set to ensure a proper fit. Finally, the re-cut threads should be thoroughly cleaned and inspected to ensure they meet the necessary specifications. **
