What oil mix do I use on this engine?
Hello. I just got a used bike from a pawn shop. The sticker on the engine says Mx5 superbike and made in korea. The engine looks well designed compared to the china engines. My biggest concern is what oil mix do I use ? I think its 25:1 on break in and 50:1 after. There isnt a whole lot on internet about this. Thanks in advance.
