Topic: cb550k1 pamco ignition timing???

[linexmatt]

Just installed the "Pamco Ultimate Ignition kit," plugs, coils, wires and module. Bike runs and starts with the slightest bump of the starter. My question is where do I adjust the timing? The terrible instructions that came with the kit say align the "F" with the notch on the engine at 1000rpm. People running the Dynatek ignition, say to set the timing to the two lines clockwise from the "F" mark. The engine seems to run much better with the advanced timing position similar to the Dynatek advised setting, with the two lines lined up with the notch instead of the "F." But, when revving the engine to 2500rpm to check the advance, both suggested ways of setting the timing don't align with advanced timing mark. Its way advanced but, if I adjust the plate, the idle timing is out of time. How should I adjust the electrodes on the timing plate? Just move one or do I move both around? Just one side? Any information would be greatly appreciated. I'm so lost.

The installation instructions for the PAMCO are available on www.cb750ignition.com

The PAMCO uses the "F" mark. If you set the timing to the full advance mark at idle and then retard the plate to the "F" mark, the idle speed will decrease. So, start by adjusting the idle to 1,000 RPM and set the timing to the "F" mark, which will affect the idle speed, so adjust the idle speed again after setting the timing.

There is an inherant interaction between the idle speed and the ignition timing for any ignition  system, not just the PAMCO. If you start off with the idle speed and the idle timing not matching you may have to go back and forth between them until they match.

Thanks for the response.

With properly set valves and synced carbs, I set the engine speed to 1000rpm and adjust timing the to the "F" mark. Then compensate the engine speed so it will remain at 1000rpm. Then the engine will not remain at a steady idle, it raises and lowers engine speed. The engine just does not seem to like it. Currently it is advanced just slightest bit passed the "F" mark and seems to run better. The bike is running UNI pod filters and a 4into1 exhaust. Will this change anything or do I need to keep with trying with the F mark? Thanks for your help! I will post a video in the AM, thanks again!

Check for the presence of a little pin on the shaft of the advancer per the instructions. If it is there, file it off as it interferes with the proper operation of the trigger rotor.

Yes, continue to set the timing to the "F" mark and compensate the idle speed. You could have other issues with the carbs as far as the idle wandering, most likely you need to sync the carbs as one of them may be right on the edge of working or not working and that could be what causes your idle speed to wander.
