There is a motorcycle maintenance training course about160m northeast of the intersection of Donghuan Road and Qianjian Road in Wanxiu District, Wuzhou City. You can go and have a look.

Tips for motorcycle maintenance: Mix a little epoxy resin glue, gently smear it along the scratches on the cylinder, let it stand for about 20 minutes, then sprinkle a layer of talcum powder, gently press it, scrape it into an arc that matches the cylinder with hard paper, and let it stand for 4-6 hours. This method is only suitable for minor scratches. If the situation is serious, change your sleeves honestly. Unscrew the spark plug, spray carburetor cleaner into the cylinder several times from the spark plug hole, then tighten the spark plug, turn on the ignition switch and pedal the car, and wait for the engine to run for a few minutes. This situation is only suitable for loose carbon deposits. If it's old gray, forget it. Slight carbon deposition, taking Lala Expressway on a flat road, can sometimes be solved.
