Fuel mixture for 66cc motorised bike.

[TheYoungPetrolHead]

I got the bike 2 days ago and I have just finished one tank of 16:1 with Penrite full synthetic high quality 2 stroke oil. I was wondering due to others saying 24:1 is the go for the break in period. Is this correct? What ratio should I use, it runs crappy at lower rpm’s but that’s what two strokes right do right? also after riding for 30mins it drips oil out of the exhaust when cooling down.

i ran 32:1 for my break in, then just left it at that.

the dripping in the exhaust is perfectly normal, its just burned oil traped in the exhaust.

32:1 break in. With synthetic. Then I go 40:1 after that. The oil dripping from your exhaust is because it's way to much oil at 16:1

Less oil is good but it will be richer fuel mixture at the main jet. You'll probably need a smaller main jet. and play with the needle clip
