oil ratio

[woody73]

Hy guys

After a bit of info from anybody who knows early 90's 2 stroke yams. I have just picked up a humber attaque with an 85hp and would just like to know the correct oil ratio mix as I havn't got any paperwork yet.

Any info would be great.

Cheers

Should be an oil injected engine, is there a big black screw cap, if so fill with oil and all will be sorted.

Hi Ian

Sorry, no its not an oil injection so have to mix oil manually!

Thanks for the reply, all my research seems to be coming up with 50:1 so thats good enough for me.
