i like using a f4 plug wrench, but the OEM tool kit contains the proper tool

 

[elskipador]

remove the plugs

we changed the plugs to CR9EIX, same resistor and heat range, but its iridium fine wire, instead of copper/board wire. if you've got a late model r1/r6/fzr/yzf/gsxr750/600 this is the plug you want...trust me

 

[elskipador]

use a little anti-seize and torque the new plug to 13 N/m

i used a little diaeletric grease on the spark plug cap/coil connections

 

[elskipador]

unplug the vacuum ports and connect the gauges

guages ready to go

this is the screw you'll be turning to adjust the sync on the throttle bodies
