I'm dealing with a slight miss at around 4k to 5k rpm, and I'm seeking some help here. It's not a bad mis-fire, but it's driving me nuts.
My 72 CB350 has always ran utterly amazing.
Recently after a ride with my vintage bike club, she starting missing really bad when I was only about a mile away from my home. Popped off the points cover and the right side points were really sparking - I knew it was the condenser.
I replaced it and the bike still had a "small" miss at 4k to 5k rpm. It starts right up, idles, and will accelerate up to 6500 rpm no problem (under these conditions I can't hear the miss). But, when I just level it off and cruise at 4k to 5k rpm there is a small miss, that was never there before. Tried cleaning up the points with no luck. Replaced the spark plugs, replaced the points with genuine Honda points, gapped them at .014, and set the timing per the manual........ No change.
Battery resting voltage is 13.0v.
Any ideas? Should I experiment with point gaps? I still have room to decrease the gaps, but I don't want to go too narrow for fear of heating up the coils.
Thanks in advance

- 3 years ago I replaced the coils
- New R/R combo unit from Sparck-Moto.
- New Motobatt battery.
- Valves are adjusted.
Thanks in advance
