Did any of the K0-K5 CB750s run a 125 main jet? I had the carbs off my K8 the other day, which has carbs off an earlier model, and I looked at the main jets and the have 125 stamped on them. I'm not sure which year bike my carbs are off, but I know it's a later model, because it has the linkage and not the individual cable connectors. The larger jet hasn't been a problem for me because I'm running pods, but the slow jet, which is a #40 on my carbs, is a tad rich for my bike. I'm going to try dropping to a #35, stock for the K8, to see if that helps.
Would the larger jet come off an earlier model, before Honda jetted them leaner to mean emissions?
