the 07 1000 does NOT like the SD plugs (ROO-45) unless you have an EmPro to put back in some timing (the SD plugs pull a lot of ignition timing!)

CR9EIX are good. Irridium more for longer life (street use)

I dont like the dual electrodes on bikes with increased compression due to detonation concerns.

Personally i have the last few years fell in love with and had EXCELLENT results on all my race engines with the Denso's. they have a std not spendy IU27A that works great in them (slightly side ground strap) and the IU31A is my personal fav..doesnt mess with ignition timing like SD plugs, but it is a low profile strap (no PTP contact issues) and its a cooler @11 heat range.

Go with the Denso's man.

I can change the ignition since I can reflash the ECU. But I think that will complicate things.

then you recomend to go with the Denso IU27a or the IU31a???

what is the strap???

ground strap..the IU27 and IU31 have a low angled side style..more piston to plug clearance. plus they dont retard the ignition timing a lot like the surface ones do. If its a street bike use the IU27A if race/hicomp use the IU31A

good luck

to open a question. Typically i would pull and clean/inspect on my top bikes every weekend. The other engines we clean/inspect (replace if needed) about once a season is all that is needed
