My son rides a DS90 2 stoke and I put a twist throttle on it. Well now I have to mix the oil in gas because it was oil injected with the thumb throttle cables. So what ratio do I use? I am sure its a very basic ratio.

 

I personally run 40/50 to 1 in everything from a weed wacker to a 500 twin. Never galled a piston in my life with this mix.

 

i run my race eton 90 at 50/1 been good all year in comp. just do some plug test's.

 

I am going to sound really stupid right now but here it goes......How do I convert the ratio down to X amount of fuel and oil. The tank is 5 Liters that is 1.32 gallons. So how much oil goes in that?

 

found a site that figures it out for you........Site
