Chain lube .for the chain.....Drain the oil out of motor and replace with oil recomended by manufacture.checkcc for recomded fluid allowance or a quart of 10 /30 motor oil is what I use..find out if he has ran synthetic oil in it before or not,for the gas and case.Dont mix them up.run your gas at a recomended 32-1 to ensure your engines safety..I always mix at 40-1 klotz,but yamalube has never failed me either..clean your air filter with soap and water,wait untill it dries and spray with a filter spray lightly.It goes along way.Always carry 2 spark plugs and a wrench with you, b8es plug size.drain radiator fluid and fill with a premixed 50/50.for your starter,contact fast racing or Jeff here on the HQ to order you a rebuild kit for your kicker.Good luck and have fun on the 2 stroke!
