Spark Plugs


Recommended Posts

I think it's 17mm,take the tank off and use a socket set or a ring spanner,try and avoid using an open ended spanner because if there in tight you will round them off if the spanner slips

Spark plugs come in 2 sizes and have there own socket as its deeper and has a rubber bung to hold the plug on removal, so if you have a decent automotive socket set it will be the large one, 21 mm,

size 1 - 13/16 (21mm) , size 2 - 5/8
