this is my first moped and it requries premix which i was unaware. so for the month i was riding it i had put the oil into oil and not into gas container. sadly this destoryed my motor and likely other parts of my bike i assume due to lack of oil. it seized on me and engine died out one day while i was riding. i need a replacement motor or else it will cost about 600 to fix which is not worth it. was wondering if anyone had any zx50 motors for sale.
