My motorcycle is Jinan Qingqi Suzuki Junchi, and I find that my oil will increase and become extremely thin. How did this happen? It only burned after driving 30,000 kilometers. ...

You don't have much oil, but your carburetor leaks oil, the intake valve leaks oil, and gasoline flows into the crankcase along the intake valve and cylinder wall.

Originally, if it was discovered in time, replacing the carburetor and replacing the intake valve would not be enough to burn oil.

It's too late now. Your carburetor, cylinder head, cylinder, piston and even crankshaft have different degrees of wear and tear. After a while, the engine will leak oil.

Because gasoline will corrode the shaft seal of the engine, resulting in air leakage and oil leakage.

I suggest you get a new car. This car needs to be repaired, either by disassembling the engine for overhaul or replacing it.
