Hey all, first I’d like to say thanks for all of the info you all have posted on this site. I’ve been able to search the site and get great advice since the start of my cb750 build.
1981 cb750c, 4into1 exhaust pipes, gpmoto shorty exhaust, pods...
Do I need a bigger idle jet if I’m at 3.5 turns out on these machines?
My question revolves around the idle fuel mixture screw. I’m following advice from others who have built something similar in the past. They recommended putting a 75 idle jet in each of the carbs and turning the idle jet 3.5 turns out. I’m under the impression (but not 100% sure) based on reading up on fuel mixture, that the idle screw should be 1.5 to 3 turns out, if it is over 3 a new bigger jet should be used, if under 2 turns out a smaller jet is necessary, etc...
