I have an 84 YT 125. the injector cut out. I blocked it but i need a good fuel ratio. the only oil i will use is golden spectro premix. what do you all suggest.

 

Golden Spectro is all I have ever used in my two strokes.

With that oil, you will want to run a 40:1 ratio. That is an equivelant of running standard pre-mix oil at 32:1

While I will never recommend it for someone else that I don't know, I run my Spectro at 50:1 and have never had an engine failure due to a lack of lubrication.[img]i/expressions/face-icon-small-happy.gif[/img]
