The motorcycle just changed the cylinder, and every time it began to cool down, it emitted blue smoke, and it disappeared after riding for a while.

Only when the cold car starts, the hot car will be gone after riding for a while. Just check that the oil is not reduced. When the cold car starts, the engine temperature is low, and the gap between piston, piston ring and cylinder body is large. There is no problem with less blue smoke emission, no smoke in hot cars and no reduction in engine oil. In addition, don't add too much oil, too much oil will also smoke.
