hey guys,
so i have the 240 big bore kit on my 1993 kdx200. I have a Wossner forged piston on it's way and was wondering if i have to use fully synthetic oil, and if i always have to use supreme gas.
thanks

Yes, you should always use premium fuel. As for oil, it is up to you if you prefer conventional or synthetic. The forged piston has no different requirements regarding fuel and oil as a stock cast piston would.
