EBU00886 Fuel Make sure there is sufficient gasoline in the tank. Recommended fuel: UNLEADED GASOLINE ONLY Fuel tank capacity: Total: 20 L (4.40 Imp gal, 5.28 US gal) Reserve: 3.5 L (0.77 Imp gal, 0.92 US gal) Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number ([R+M]/2) of 86 or higher, or research octane number of 91 or higher. If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel. Unleaded fuel will give you longer spark plug life and reduced maintenance cost. Gasohol There are two types of gasohol; gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if ethanol content does not exceed 10%. Gasohol containing methanol is not recommended by Yamaha because it may cause fuel system damage or vehicle performance problems. CAUTION: _ Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to the engine internal parts such as valves, piston rings, exhaust system, etc. _ 5-4
