My own PWKs which I am now replacing with Keihin FCRs. Rubber boots, throttle, throttle cable, extra mainjets and instructions included. These are great carbs. Tuned for 750/850. I used to sell these before I switched to Keihins. I'm selling them because I decided to run what I'm selling now. Add our intake manifolds and aftermarket pod style aircleaners if you need them.
