Do I need a special hone to hone the cylinder on a 700?

If it needs to be honed more than likely it needs to be replated. You can hone them with a diamond hone but the factory Yamaha coating is only like .004" thick.

Im replacing the piston and didn't like the idea of not giving it a light hone before doing that. Its not scratche or scared in any way that I can see

Some like to hit it with a scotchbrite pad, others will tell you not to touch it. Either way, steer clear of the traditional ball and bar hones, they'll remove way too much.

Yep, just use some brakeclean and a Scotchbrite pad and clean it good. Dont go up and down the bore, go around the bore in that motion.

well since you guys are raptor guys ill probably do that. though, i just got off the phone with alba (was ordering other parts) and they told me to make 4 passes with a ball hone. considering the scotch brite meathod isnt going to cost me 70 bucks ill probably go that route lol.

OUCH. If they're telling you to use a ball hone I would seriously question their knowledge about this and steer away. You definately don't want to use a ball hone as that will only follow and exasperate any iregularities in the bore squareness and taper.
As a shadetree mechanic tactic when you can't get it done properly with a diamond hone you can deglaze the cylinder using some scotchbrite. Try and follow a crosshatch 30* X 60* pattern and wash the cylinder clean with hot soapy water. If you find anything on a white cloth when drying, wash it again.
