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 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. **

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 RPM (Revolutions Per Minute) of the crankshaft is a measure of how fast the engine's crankshaft is rotating. The RPM of the crankshaft can vary depending on the engine speed and gear ratio. In a typical car engine, the crankshaft RPM can range from around 600 RPM at idle to over 6000 RPM at full throttle. The RPM of the crankshaft is an important factor in determining the engine's power output and performance. **

The crankshaft gear can be saved by ensuring regular maintenance and inspections are carried out to detect any signs of wear or damage early on. It is important to use high-quality lubricants and ensure proper lubrication to reduce friction and wear on the gear. Additionally, avoiding excessive loads and sudden changes in speed can help prolong the life of the crankshaft gear. If any issues are detected, it is important to address them promptly to prevent further damage and ensure the gear's longevity. **

Yes, the crankshaft on the Velosolex should be tight to ensure proper functioning of the engine. A loose crankshaft can lead to issues such as loss of power, engine misfires, and potential damage to other engine components. It is important to regularly check and maintain the tightness of the crankshaft to prevent any problems while riding the Velosolex. **

The speed of the crankshaft in an engine is measured in revolutions per minute (RPM). The exact speed of the crankshaft can vary depending on the engine design and its intended use. In a typical car engine, the crankshaft speed can range from around 600 RPM at idle to over 6000 RPM at full throttle. The speed of the crankshaft is crucial for determining the engine's performance and power output. **
