Racetech as yet does not list the NC700X on their on-line application chart. Did they tell you what Gold Valve Emulator kit number was used on your NC?
Well, they have done two of them now, so they know what fits it. I got the S4101NV Gold Valves with S3534085 springs and am using USF-05 15 weight oil. The best choice for you may depend on your intended use. Mine was spec'ed for Dual Sport Intermediate 195 lb. rider. If you want them to reference it, the shop order number was RT9085.
