First off, my 77 cb750k came with pods on it already and 120 mains... previous owner couldn't get it to run right, i picked it up for a song. I found a float installed upside down, fixed that, still wouldn't run right, so I cleaned the accelerator pump circuit and the primary jets and got curious about the needle position with the 120 mains, needle was on the leanest setting, well that explained the lean misfire at 1/8-1/4 throttle, clip to middle of five position choices... reassembled the carbs and it ran great, even started with no choke cold... I ran it for a bit, it idled rich so I turned the idle mixture screws in and in some more, leaving them 1/2-3/4 turn out from seated. So, the bike ran strong, good low end and strong mid-range, but choppy and rich at idle, and I had a bit of a hanging idle as well, it took a few seconds for it to settle at a stop sign or between shifts. Turns out I has installed the slides backwards... (anyone else done this? be honest.) I have since flipped the slides back around and I'm still to lean on the pilot jets, I have some on order from Sirius, the only place to get the friction fit primary jets. Oh yah and I'm back to three and a half turns out on the mixture screws. I'll up-date on my progress in seven to ten business days.
