Why is there a noise when the rear wheel of the scooter rotates?
1 Answers
The abnormal noise from the rear wheel of the scooter could be due to a damaged rear wheel bearing, but it might also be caused by long-term wear of the pulley sleeve. However, the noise caused by the latter should not be very loud. If the issue lies with the pulley, it can only be resolved by replacing it with a matching part of the same model. It's best not to use automotive engine oil in motorcycles, as their engine speeds and temperatures differ. However, for small-displacement motorcycles with low usage intensity and load, using it doesn't present any significant problems.
