Running in

[Chilli]

Hi guys, i am in the process of running in my LI silver special (175cc kit), its currently around 200mls in, i know i have a way to go yet but when do i need to change the oil to fuel mix, at the moment its running in on about 3.5%, cheers in advance

Not sure why you settled on 3.5% but whatever, you don't need to change your mixture. People do change oils to aid running in, but that's different. Generally speaking use a good semi and stick to it.
