Top price and delivery to New Zealand was FAST. Make sure you order new flanges and seals though as kit does NOT have them.

I ordered this for my wifes 98 Low Rider. Just comparing side by side this is a way nicer carb that the factory HD. Installation was pretty easy would of been nice with better directions but we figured it out. Does not come with intake seal so order them at the same time. Its winter in Montana so I have note rode yet but started right up, idles great and throttle very responsive. Very happy with the way it runs can not wait for warmer weather to ride.
