I already proposed a reason to such a behaviour. The electolytic capacitors in the cdi loose their capacity when getting old. When hot, they loose a little more. The bike thus doesn't start any more, until the cdi cools. And when cold, it's nearly impossible to adjust perfectly the idle engine operation, because out of the two ignition chains on the cdi, naturally one looses it's functionnality before the other due to dispersion in capacitors characteristics.
I bet that within 4 years, all 1982-1984 CBX bikes will have the same behaviour. I'm presently trying to find a small electronics company around here to change all the electrolytic capacitors and, in the same operation, change the transistors by new ones less subject to failure than original ones. Of course, buying a newly made cdi at a Honda dealer - not a cdi stored 20 years in a warehouse - would solve the problem. Along with the alternator / regulator flaw, this makes these bikes a great pleasure for electrical engineers.
