Got an '81 CX500 Custom last summer, aprox 53,000 miles. Assumed PO did nothing, so I changed plugs, oil, rear end oil, air cleaner, and anything else I could think of. Ran SeaFoam through the fuel system. Several times. Over winter, cleaned out the gas tank real good (it wasn't bad, though), rebuilt fuel petcock.
I notice a miss at about 5200 rpm (5000 to 6000) that's not constant. As in it seems to hit on both cylinders, then several misses, then it's OK, etc, until you get out of that rpm range. It's the left cylinder according to the spark plugs--that one's a little darker and wetter, though not bad. Just not as normal looking as the other one.
I don't know that the carbs have ever been apart, so I was thinking of swapping out for some that Larry has rebuilt (he seems to be the end-all in that department). Was also thinking to replacing the coils or maybe the whole ignition system with an updated one. I don't know which end to start with, the carburetter or the ingition.
Ideas?
