oh yeah...removed mine so long ago i had forgot about it...and the joys of changing plugs with it in situ.
I use iridium plugs, seem pretty good. If You use the yamaha spark plug tool make sure it has the rubber insert iniside it (mine didnt!). it grips the plug.....and with out it....it....well doesnt :rolleyes

Don't know what all the fuss is about. Never had a problem even with the AIS in place. It's a bit easier once the AIS is removed... But using the spark plug socket in the Fazer tool bag is always the best option.

Buy a torque wrench! After that, it's a 15 minute job. You should try changing the plugs on my ZZR if you think a Fazer might be difficult. Honestly, it's a doddle.
I do wonder just how often they need changing though. My iridiums were fine after 40,000 miles and the only reason I changed them was because I'd already bought new ones and I thought 'may as well'

I used to use Iridium, and thought they were the canine dangly bits. Couldn't afford them one year and went back to standard plugs. And thought they were the canine dangly bits too. It took a while, but I finally learnt that it was the fact that the plugs were new, not what they were made of, that made the difference.

Iridium plugs just last longer, so if your changing them at specs interval then not worth the extra dosh. but if your likely to let them run longer than that they do stay fresh for longer.
i tend to use them because i had an old ZX10 that ran rough as bugger and improved a huge amount with iridium plugs, swapped back to fresh std plugs and ran rough again.
now it clearly had an underlying problem but back then plugs were about as far as i ever went lol and if they made an improvement then they had to be better than normal ngk ones.
now i know better but i do still try when able to stick with the iridium plugs. even though i know they realy are not a wonder plug just a good plug.

+1 for using the yamaha tool for this job, then its not a problem even with the AIS still in place.

to be honest I don't know what a ais is but I just used a normal plug socket and changed them without any difficulty

AIS air induction system or is it air injection system anyway its a way to avoid emmsions problems in certain countries, it nmakes little if no difference to performance and can be remnoved with a suitable kit, like the one Justy used to supply, it makes servicing easier if it is removed

Thanks folks for your help and advice, I have the yamaha plug tool so I'll have a go with the AIS in place. Great site....
