I've read that too, but I have 2 Banshee with 2 different model ASV's and no problem. I have seen some aftermarket perches require a ferrule to space the cable housing.
Here's a Yamaha part number trick. Your bolt is # 97017-06010-00 The center set of numbers tells us it is a 6mm by 10mm long bolt. You just have to know the 6's are 6x1.0mm thread pitch.
Keep in mind that at only 10mm long a bottom tap may be required for that hole. I believe it is a blind hole.
