    Lightbulb need a pilots licence fer me ATC 270R?!

    hey,

    i have plans in the workings for my '83 atc 270r (bored 0.030" over)
    am planing on getting the Keihin PWK Air Stricker (35,36,39mm) Boyesen Rad Valve and a DG Exhaust. i also have the '84 top end on her for the better compression ratio. i smoothed the ports for areo dinamics.
    But i'm not too sure as to what size of carb to get, any input from you pro's would b exellent!! i kindda wanto get the carb in about 3 hours lol

    Thanks in advance!!
