So I just bought my little cousin a 49cc coolster dirtbike. I know you mix oil and gas for the fuel but I'm not sure if it uses oil in the transmission. It is an automatic with centrifugal clutch. Please inform me.
if so, no they dont have any oil in the transmission (there's no where to put it anyway)
you'll need to get some 2T oil for premixing
if the bike is new, then you'll need to run it in with a ratio of fuel/oil around 25 to 1, 2.5 litres petrol to 100mls oil
once you've ran a couple of tanks worth though the engine then you can run it at 32 to 1.
Yes looks just like it. So I have read with centrifugal clutches you should squirt some oil behind the snap ring so it lubes the bearing. Is that the case with this bike at all or no lubrication needed?
