So why do you run a DNA pulley for years but don't recommend them? 
....
Pulley are made to be 1 1/8" to fit a 1" belt. Even a stock pulley is 1 1/8".... to fit a 1" belt.
Here's a link to a 70 tooth pulley 1 1/8" 2000+ .... don't know why it wouldn't fit but there it is.

Saying why I don't recommend DNA is a no brainer. Since I have experience with them in the past plain and simple they are a crap shoot. Some have had luck with them and most others have not. I would never buy their wheels as I feel they are junk. That's my opinion though that seems to be verified by others. The rotors and pulleys though are not that bad. I bought the rotor long ago and the hassle I had to go thru with them I just ended up keeping it on since it was already on. It has pitted over the years though so I will replace it with a new one soon but it will be a proper 1" pulley. Since I am going with hard bags I don't really need something really fancy.
You can use the one that you posted in the link. You will just have a 1/8 gap on an 07 or later due to the 1" belt. You will also need the 1/2 spacer they sell... although when we measured it out I ended up going with a 3/8" spacer. It just aligned the belt on the opposite side.

I believe this is incorrect information. Inside track for the DNA pulley that they sell for 07 and above is 1 1/8. I have an 07 and the belt is 1". I measured the DNA pulley and it's 1 1/8. I have an 1/8 gap between the belt and inside wall of the pulley. My stock pulley did not have that. I will get it down from the loft later today though and measure to be sure.

And as for DNA products im sure your statement there is incorrect also.... Yes they have thier problems but most of it works and thier are some that don't... Just like all products from several different manufactuers. So out of the 1,000,000 + pulleys/wheels/rotors sold... I've only read of a VERY small percentage of thier produtcs failing.... I've owned 2 sets of SS rotors... 2 sets of wheels... 1 SS pulley... i guess im lucky eh'.....

Thanks for the additional input guys.
FYI - the stock pulley on my bike is indeed under 1"... here's a photo I just shot when I remeasured:
Leave it to the MoCo to not only screw up the gearing on the change, but also to have so much inconsistency in the model specs!
I'd prefer to have an exact fit and not have to screw with trying to patch one in with spacers and such, as I certainly don't want a failure when taking advantage of the additional torque.
Just another example of how the '07 is a bit of an enigma I suppose.
Thanks again guys!

Yeah, it is actually right around 7/8" - I found one post that referred to it as 20mm, confirmed in my service manual. FXST, FXSTB FXSTC and FLSTF use 20mm.

Mine is the same way Tunaman.
What the moco did was beveled it down on the inside. You can't see it with your belt on but if you look at the pulley from the top it's narrower at the bottom than at the top. Not a lot but it's there.
Blcknchrome is correct in a sense. On my 07 stock pulley it's more like 1 1/16. So it's a little wider than 1". I just didn't remember the gap on mine such as what you have but it is what it is.
The DNA pulley though is 1 1/8. No bevel. So the 1/8 inch gap is more noticeable. Still though, you can run it. I will even sell you this one I have. Never been used.
Oh wait... u want a 70th...
And blacknchrome... my opinion of DNA was just as I stated it to be earlier. My opinion. I will never run their crap on my bike again. I have read the threads before when people ask about DNA and see what the responses are as well as my own personal dealings with them. So fine. I will go it's a 50/50 crap shoot with them (and that's stretching it) but no not all companies are like that. Ride Wright being the biggest example.

What a PITA... nothing is ever simple! 
If one of you have both 66 and 70 tooth pulleys in hand, could you please measure the outside diameter across? I guess the biggest factor right now is whether I can fit a rear 70 tooth without having to replace my belt, or whether the belt will need to be replaced regardless. I'm really hoping not to have to pull the swingarm to swap the belt.
If the belt needs to be replaced, then I guess the better solution would be the Andrews 30t and a shorter drive belt, although that would then put it somewhere around the same costs as the Evo clutch gear, which doesn't require a belt change or cracking the inner case. SHEESH... keeps sending me in circles!

I don't have a 70th to measure. I would be surprised though if you can make a 70th work on your 07 but maybe... just maybe you have a little room. Like I said. My buddy couldn't make it work on his standard. Maybe now your belt is a little stretched?? I dunno.
I dunno.
