Hi I might be getting a HIF44 carbie soon; complete with manifold, throttle bracket, air filter - ready to bolt on.
I was just wondering what sorts of differences i could expect using this over my 1.5" carb that I have on it now.

Also, i would probably need to get needles for it so it runs nicely with my engine; its a 1100 (1132). What do needles cost? And could i change the needles and tune it up myself?

Thanks.
