I once went on a date with a girl who had a showroom quality CL350. I remember trying her bike and remarking how it purred at a rock solid 900 RPM.
How can I dial in the engine like that on my Cb350? I've followed all the important tune-up procedures. Adjusted valves, set points timing exactly, dismantled and cleaned carbs, bench sync'd them, perfectly set both throttle cables. It idles at 1000 RPM but I can hear a little bit of roughness, a tiny unevenness to the rhythm, and if I leave it long enough sometimes it dies.
A few questions:
- when I set the timing, I didn't adjust the points gaps as the Common Motor Collective guide I was following said that doesn't matter as much as the timing itself. What effect does dialing in the gaps have on the idle performance if at all?
- How are we expected to perfectly sync the carbs on these engines without vacuum taps? How do people on here do it?
- Common motor collective's bench syncing video suggests 2 turns out as a starting point for the idle mixture. What do you guys set it to to begin with?
