My friend has just been given a 1978 TS125 Suzuki he's not sure what fuel he should be using 91 or 96 or what is the best fuel mixture ratio any ideas would be great

95. And it should have an oil tank!

he can use either 91 or 96 as it is a two stroke. the oil is more important. 25:1 to 33:1 fuel oil ratio should suffice for an old bike like this. Nz tools is on the right track and this bike should have a separate oil tank for the two stroke oil but the pipe often clogs , air bubbles in the pipe and the pump can fail. so premix might be advisable.

Thanks so much NZ Tools & beno, the oil tank has been bypassed so he is having to mix it himself
