What spark plugs do I need for my '97 YZ 125? Bought the bike a few days ago... I have a service manual on order but would like to buy some new plugs tommorow.
the eg is a racing plug, i ride the eg on the track, and the es on trails. the eg runs hotter and is more of a performance plug, it doesnt foul near as much. although it is a little more expensive, that is why i only ride them on the track.
