    CB500F carb jetting

    OK, simple question. I picked up a cheap 73? CB500F. The guy I got it from threw away the airbox because pods are so much cooler right? My question is how hard is it to get the jetting right on these carbs? Am i better off trying to find an airbox? Some carbs on my other bikes are easy, some are hard(jetting). I dont have any experience with these particular carbs. They look very similar to SOHC CB750 carbs to me. Any one messed with these? Any jetting suggestions? Just one size up for idle and main? Box or jets?

    Easy.
    102~105 main, float level +1mm drop needles a notch

    Ok, for the needle setting, which groove? My manual says stock is 3 down from the top but they were set 4 down from the top. Looks to me like no one has been in these carbs. Should I make them 2 down from the top then? Drop 1 groove from where? Maybe start with 103 mains? Thanks.
