New Street Demon carbs

Get the composite body version, and the tuning kit. While you may luck out and it'll be a bolt-on and go carb needing only idle mixture and secondary air door adjustment, just expect to have to tune it a little. Only issues I've seen is on the 750 I was using is the ford kickdown linkage somehow was causing the throttle to hang up occasionally, I cut it off problem solved. And on both my sons 625 and my 750 the choke flap would sometimes get stuck when closed, hyper extending in the tower. A small washer under the air cleaner stud nut was all that was needed. The washer hangs out just enough to act as a stop for the choke flap when it closed
