Hard starting, misfires or a rough idle can mean a plug is worn, though an ignition coil or fuel supply fault can produce them too, so find the cause first. With the engine off and cool, look at the electrode and insulator for wear or cracks, and measure the gap against the 0.036 in (0.9 mm) listed below.

Fits

It is listed for a wide range of Yamaha models, including the 2018-2019 Yamaha MT-09 847cc and the 2019 Yamaha Tracer 900 847cc. Owners of other Yamaha models can find their bike by year and engine in the "Vehicles it fits" section. The plug suits bikes fitted with nickel alloy plugs from the factory and is not recommended where the factory plugs are precious metal. The 847cc engines take three plugs and the 1298cc engine takes four.
