Fuel Make sure there is sufficient gasoline in the tank. Recommended fuel: UNLEADED GASOLINE ONLY Fuel tank capacity: 24.0 L (5.3 Imp gal, 6.3 US gal) (YXP700) 30.0 L (6.6 Imp gal, 7.9 US gal) (YXP1000) 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 internal engine parts, such as the valves and piston rings, as well as to the exhaust system. _ 5-4
