What oil mix do I use on this engine?

[onkyo]

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.

mx5 superbike engines are great. you're meant to run 50:1 the whole way, but if you don't know the history of the bike I would try 40:1 and go from there

Thanks! Do you know anything about the spark plug? Type,brand,gap?

should be something like .030. don't remember what plug they come with.

I started the engine for the first time today. Mixed at 40:1. She runs great! Thanks again.
