CB750 K5 things to check for a intermittent idle RPM or hanging idle? Got timing dialed in, was retarded a bit and off a few degrees from one pair to the other. Throttle linkage adjusted, cables routed nicely, etc. Fixing the timing seems to have made it worse, which makes sense that it would want to rev easier with more advance. Swapped in fresh iridium plugs. Love those things, they'll just about split the hydrogen out of water and ignite that. Otherwise ignition is points, factory coils, factory wires.
Tightened carb boot clamps. Have not had this rack off but boots feel reasonably soft. Idle air screws all about 1.5 turns out, little effect adjusting them so left them there. Idle screw seems to have little effect backing out past a certain point, either high or stall once warm but occasionally idles nice(ish) around 1200 (closer to 1000 says my timing light). Suspect I just need to stop being lazy and get my bottle and gauges set up to vacuum sync them. What say you guys?
