Hello.
I am new here and looking for some advice.
Just bought sfx 50cc for my son, but motorbike start hard and badly smoke when started (blue smoke).
I assume that is a bad mixture between oil and petrol (2 stroke engine).
Scooter have separated tank for fuel and oil and do the mixture by themself.
I try to locate some screw for adjusting mixture but without success.
My question is can I block a oil tank and do the mixture in petrol tank only?
Many thanks for answers

 

yes you can take the oil pump cable off anf block the oil tank. mix i believe 50 to 1 after. check and see if it's been done already and someone also put oil in the gas tank. usually the oil pump uses less oil and less smoke so it may not smoke less if you do it. find a manual and see how to adjust the oil pump.

 

Thank you for reply. I will give a shot on weekend
