Motorcycle chain tightening and loosening intermittently is mainly caused by loose fastening nuts. Check the condition of the chain: The pitch of the sprocket teeth may have errors. Although sprocket processing is precise, small batches are often cut with wire or milled with a milling cutter. Solution: If the chain is damaged, replace it directly. If the chain is intact, pre-tighten it first, adjust the chain tension, and then fully fasten it. Check the cushion shaft: Apply grease regularly. Since the working environment of this bearing is relatively harsh, failure to lubricate it on time may cause significant damage. Check the front and rear sprockets: Check whether the front and rear sprockets and the chain are aligned. If they are not aligned, perform maintenance.

Can I change my existing license plate if I don't want to use it anymore?

Unless under special circumstances, it is not possible to change the license plate number. A vehicle's license plate is like a person's ID card and cannot be changed at will. If there are special circumstances requiring a license plate change, the following procedures must be followed: 1. Apply to the traffic management department to cancel the original license plate. The traffic management department will review the driving license and the violation records of the plate before approval. 2. Publish a license plate cancellation notice in a local newspaper (the traffic management department may also issue a cancellation announcement). 3. After 30 days, the vehicle owner must bring their ID card and the original vehicle purchase invoice to the local traffic management department to complete the new registration procedures. Relevant information about license plates is as follows: 1. Introduction: License plates, commonly known as vehicle plates, refer to the plates displayed on the front and rear of a vehicle, engraved with the vehicle's registration number, registration region, or other relevant information. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their primary purpose is to identify the vehicle's region of registration and to trace the vehicle's owner and registration details through the plate number.

Is it okay to leave a new car unused for 20 days?

It is generally fine to leave a car unused for 20 days, but it is recommended not to leave it parked for more than half a month. The potential harms of leaving a car unused for an extended period include: 1. The battery may lose charge if not recharged for a long time, making it difficult to start the car; 2. The tires may deform due to uneven pressure if left in one position for too long. Precautions to take: 1. Park the car in a garage and cover it with a car cover to protect the paint from sun, rain, or falling leaves; 2. Do not engage the handbrake, as the brake system can react with moisture and oxygen in the air when left unused for a long time, leading to rust on the brake discs and pads, which may cause the wheels to lock; 3. Disconnect the battery if the car will not be used for an extended period to prevent power drain from onboard electronics; 4. Check the tire pressure of all four tires to ensure they are normal and there are no leaks.
