Im pretty sure you can run it from like 35:1 to like 50:1 Im pretty sure you can run it from like 35:1 to like 50:1 because i run my motor scooter 40:1
About 35:1
try 32:1
25-1 running in period for first 3 tanks 50-1 after that
Fuel mileage is about 25-30 MPG depending on how you ride it.
I spoke to a dirt bike mechanic who said that two and a half turns on the air/fuel ratio screw from the closed position is a good starting point for this particular bike.
I have a 1998 CR250 and i mix it 32:1
it depends really i have the same bike and i do 40:1 ratio that's 16oz to every 5gal of gas
A CRF 50 is a four stroke, no premix on this bike.
its says to use 32:1 ratio, if the bike has a fresh rebuild of the cylinder and piston use 15:1
Hi, the fuel mixture for a YZ85 is 40:1 and I recommend using good oil. I run Amsoil Interceptor synthetic, the bike runs great on it because it burns very clean and it keeps the inside of the motor clean
There is typically a mix of fuel used for motorbikes such as the 85KX, as petrol and oil are usually mixed together for usage in the bike. A ratio, for example, might be 50 parts petrol to one part oil fuel.
usually any type of 2stroke air cooled blend... the fuel oil mix for poctet bikes is usually 50:1
