Also I just received the Clymer manual and it said to test the resistance between the white wire and black wire from the stator and upo testing them I got a reading of 1 ohm when the specs are between .4 and .6 ohms. Both results point to a bad stator but it still does no address why the bike is moody. The smell of gas is overwhelming when the bik is running leading me to believe it is running rich. But that does not explain why all of the sudden it go from running ok to missing and backfiring all of the sudden. It seems that letting it sit overnight ensures that it will run well for a little while the next day an then go back missing and backfiring.- If your spark is really weak, it can't ignite the fuel air mixture properly and it will kick out a lot of unburned hydrocarbons. Also, if the motorbike has sat for a few months without being ridden, you'll smell some horrible odors coming out the exhaust. Compounds called aldehydes break out of the gasoline molecules and and they really stink. Now, I'm wondering about the black wire and the white wire you mentioned. What is their function? I thought you said that the stator outpu wires were yellow, that you also had a red/white wire, a green wire and a black wire coming from the regulator. Some Hondas had excited field alternators. They had a white wire and a black wire going to carbon brushes on the alternator. The brushes conduct current through the slip rings on the rotor and it becomes a rotating electromagnet, inducing current into the stator windings. Does your alternator have brushes? There are no brushes shown on the parts fiche for the 1983 CB550 Nighthawk at [URL="http://www.partfish.com"]www.partfish.com[/URL].[/QUOTE] Krusty, Well as the old saying goes "more will be revealed." I believ the alternator is brushless. I have conducted yet another test found i the clymer manual. It is the test of the ignition pulse generator. Th test has you check the resistance of both pickups. The correc resistance is 330 ohms. One pickup tested fine. The other had n reading at all. If my suspicions are right I will check this again thi evening after letting the bike sit all day and the one that tested ba will test good. I believe this will be the case because the bike run fine when it has sat for five or six hours then as it heats up it run like crap. It would really be nice if I could talk with you onth phone. I would understand if that is not convienient for you. You hav been a great help and I appreciate your help very much. If we coul talk you can email me your number at [email][/email]
