Re: what did you do to your motor bike today?
16:1 is way too rich. 24:1 is better for a start. Two tanks of that then 32:1. The 16:1 thing is for low quality oil or even used oil. Modern oils are much better than any Chinee oil.
They are some here running Opti oil at 100:1. That's a little thin for the old racer in me but I'll be running 50:1 with Maxima Formula K2 oil. It's very expensive at $10 a pint. I used Maxima oil when I was racing a RM250 Suzuki on a SuperKart and never had an oil related problem. Just make sure you get an oil specifically made for air cooled motors. The water cooled motors do not run as hot and the Chinee motor really needs the extra protection.
