I have not changed mine yet so I cant tell you exactly how to move the radiator, but why do you need to change them?
The plugs should be good for 25 to 30K.
Most manufacturers tell you to change them at blah blah blah because they know you cant and will take it to the dealer and pay them to do it.r
Overchange your oil, underchange the plugs.

I don't have the bike near me, but I believe there are 2 5mm bolts at the top(one on the left and one on the right), and one on the bottom at the center. When I did my plugs I completely removed the radiator, so I also undid the hoses.

yeah once i got all of those off it didnt seem like it gave enough clearance to get to the plugs without removing the hoses. i don't want to do that.

Mine looked like new, but I just figured I'd put some iridium plugs in.

I would check with the manufacturer of the plugs. Most plugs now are being made with coatings on the threads where this is no longer reccomended.

I'de rather be safe than sorry.......regardless of what "they recommend", this anti seize method has been used in tons of applications, world wide, for decades and it is time tested, maybe the new teflon shit works..........but not for me.........
And use a torque wrench.

If you use NGK Spark Plugs adding anti-seize is not recommended as per NGK's instructions for new plugs. They already have a coating for this issue.

It is possible to do this job without removing your radiator completely.
http://www.779cc.org/forum/how-tos/1682-tips-replacing-your-spark-plugs.html
There are 4 screws:
1 Above the radiator on the right side (Left side is just a hanger.)
1 Below the radiator
2 One on each side that hold tabs onto the frame.
Pull to one side to remove from hanger then drop down.
Just that easy. Well if you have the service manual its that easy. It tells you how to do what you are asking. Plus all the torque specs for putting it back together.

Spyder Eye is right and he includes more detail than the Yamaha service manual. I have not changed my spark plugs yet, so I have no pictures. If you have all those bolts out and it's off the hanger, then it'll only be the hoses holding it in place, they are rubber and will bend.
If you are a bit of a heavy handed person, get a torque wrench as the plugs are only done up to 13Nm. Over tightening is the most common reason why they won't want to come back out again. Then you risk damaging the thread trying to remove them.

i'm thinking if i do it i need to get a low torque click type wrench instead of my metered type. that looks like a very tight squeeze.

I agree that a clicker style torque wrench is best suited for this job. Also having an assortment of medium to small length extensions is key to finding the right length for the space available.
