So i have a kitted za50. the kit is a polini 64cc, currently the engine is all in pieces but it is all there and ready to be put back together. The only thing that you would need to buy is cylinder studs cause one is off and one is bent and a piston ring because it had a light seize. I am looking for an e50 kitted or an e50 and enough money for a kit. Let me know what you got.
