Anyone know what size adapter I need to use it on an '04 GSF?

Yea you want blue. That is the fastest color.
Colortune is for Idiots who dont know how to jet a freaking bike. And no its not you ...
Maxim Idiots swear by it, so do virago clowns ... XS650 dolts buy some funky ass adjustable needle one guy on that site sells. They all need +1 over stock for mains and virago needs pilots too. Look in the manual and see what they put in a bike that went to some third world corner wth no EPA junk.
Jetting is not that hard guys. Dont throw all the extra crap on it, you will easily shaft yourself.
BTW you jet it with an O2 sensor. Get one off a 92-94 cavalier, weld a bung in the header and tune away. Its however not neccesary. The tried and true formula works well.
Cool.

See! The Buddha agrees with me.
In order of fast color:
Blue
Black
Red
Purple
White
And custom colors, they get outrun by '78 civics.
i just googled colortune cause i didnt know what it was. that seems pretty cool, why dont you like it buddha?
A clear spark plug that allows you to see the color of the ignition flame for tuning. I'm not sure if this answers the original question but the GS has a 12mm spark plug hole.

^That is the answer. Thanks!
I don't want to rejet it, I just want to fine-tune the mix screw settings. I already use a Colortune for my XJ, so I figured I'd try it out on the GS.
I am sensing some bitterness here...
Not bitterness just some iluvyoubuddhaing going on is all.
Colortune??.....some people swear by them, some people swear at them. It will never change :D
Lets try this. Ride down the road. And see your spark plug porcelain area for color ... and yes please try it n daylight, and tell me what color you see ... unless you're doing your speed runs @ night ... then, by all means do it at night.
Oh, you're sitting in your driveway and tuning it ... then why not just plug pull ?
O2 sensor to digital read out is much safer, more user friendly and a lot easier ... and doable in the daytime.
Its a cool but worthless product ...
BTW on a 4 cyl, you can have the 2 center ones run different than the outer ones ... so you have to do it on both.
On a V twin, front to rear can be different.
Usually on a GS left vs right is not too far different ... so you can pick your preferred side to tip your head while running full throttle ... you know to see the plug. Always a great idea.
O2 sensor in the pipe ... for those of us who're not endowed with eyes with ability to distinguish colors in a tiny spot in the midst of all the vibration and wind in broad daylight, fitted in our knees.
Yea dude, buy a colortune ... so when it doesn't work I can buy it off you dirt cheap, and use it on my xs ... which has plugs sticking in the breeze ... just about the only bike a colortune will be useable on and yes I would run it at night to see the color.
Cool.

huh! Never heard of colortune. Interesting....
Yea ... cos its idiotic ... lets see a plug that is made of some transparent material that lets you see inside the combustion chamber ... yea ... very practical and useable there ... supposedly you can see inside the chamber ... how you're gonna do it while riding is beyond me ... and if you're doing it sitting in your driveway ... just pull a plug and see it.
Cool.

I gotta disagree with you on this one buddha, i think itd be a great way to tune it. the way you ride and see the plug at the same time is on a dyno, or some kind of spindle that will resist the the rear wheel a little bit. But you said rejet is much better, but rejeting still needs a way to get the mixture screw just right.
now ive never used a color tuner, so my uneducated opinion has little merit, but, in theory it seems that this would be a very useful tool. if you have a safe wheel to simulate load.
This is how I used the colortune on my XJ650: I install the transparent plug and run the engine idle my driveway (at night because I have a day job and its now dark before I get home). The color of the combustion was deep orange, indicating a rich condition. I turned the mix screw on that carb until the color of the combustion reaches white with a hint of blue. Reinstall the normal plug and move on to the next cylinder. Afterwards, my '82 yamahur is purring smoothly.
Mind you, this is after a full valve adjustment, carb clean, and vaccuum tune on a 28 year-old bike. Everything is to spec except the mix screws, and this is one easy way to fix that. A Colortune is used to fine-tune the IDLE of your vehicle. Theres no point using it while riding the bike - in fact that will probably destroy the instrument.
So you use it cos you're too lazy to do a plug pull and adjust ... cos reading a plug after a driveway rev is just the same.
BTW the one bike in the world other than a XS the colortube can be used on is a maxim, its got plugs in a nice well and you can see it sitting on it.
If you need to tune idle I'd say plug pull, and second option IMHO is the high idle when hot. low idle when cold starting ... AKA richen it up.
Only tuning really needs to be under load, cos you're never going to kill your bike just idling it. The running hot and heat seize ... never happens in the real world @ idle. High rpm under load + lean = over heat and seize.
Cool.
