Hello, I'm new to the site and hope to get the rite info.
I've been given a Ducar 125cc dirt bike for my son, we just can't figure out the correct fuel mix, the previous owner told me 4stroke fuel, tried that but it won't start. I'm thinking 2stroke mix but at what ratio would it run the best?
Hope someone can help, cheers
Hey bro it's jazz from YouTube
Figured you no best I'm looking to do a 4 valve yx motor for my 110 can you get the 4 valve head for yx150 or does it have to be 160? And if not does the bbk for the 150 that takes it to 170 compare to 160/184 kit
Or would just a 4 valve head on a 160 be better than 170 kit on 150
