I always run 32:1 full synthetic 2 stroke oil after break-in is completed...My bike is smokeless with the full synthetic and has great lube protection...I would never run less than 32:1 mix...4 ounces full synthetic 2 stroke oil with one gallon of ethanol free gas if you can get it...Ethanol has a bad habit of eating away at aluminum and crank seals as well as screwing up the carby's...lol.80cc
40:1 or 50:1
U kinda loss me see I bought this bike off a guy and im new to this he didn't tell me about all these things
