I think I just wasted 20$ on a carburetor "tuning" manual. The information in it was helpful for tuning but the information I'm looking for is determining an initial body size and calibration for a given engine. There is a ton of charts and calculations out there for automotive applications but where are they for Mikuni carburetors? I haven't invested days in searching yet but I'm getting tired of combing through the ads in search of what I'm looking for. If any of you could help, I would greatly appreciate it. I am trying to avoid hundreds of dollars on jets, needle ect. just to get in the ball park. I have my CFM, VE, F/A ratios , on and on and on. Just looking for a chart as to fitting slide, needle jets, needles and mains. Thank you.
