Get to the head

To reach the plugs you’ll need to gain ac­cess to your bike’s cylin­der head by re­mov­ing the fuel tank and air­box, make a note of where any breather pipes or fuel hoses go so you can re­assem­ble them eas­ily.

Note the num­bers

Make sure the ig­ni­tion is switched off. Each plug cap should be num­bered so make a note of which one goes where, then ease off the plug caps and re­move. Dis­con­nect the HT leads from the plug caps.

Get the right tool

Get­ting hold of the spark plugs re­quires a spe­cific wrench that should be in your bike’s tool kit. Com­bine the key with a 3/8in ratchet and ex­ten­sion for eas­ier ac­cess then re­move the plugs in turn.

Be the boss

Some spark plugs re­quire fit­ment of a boss on the ter­mi­nal so check to see if your does and screw it on. In­stall plugs and torque to the cor­rect value. Re­fit the caps and leads, and re­place air­box and tank.
