Once I look at the section referring to the rectifier I will try your fix.- I don't know if you understand the nature of Mark's solution to the remote sensing wire problem or not. If the remote sensing wire is open or has high resistance, the voltage regulating circuit in th rectifier regulator won't work and the voltage will get too high. That's which Mark moved his wire, he wanted to avoid burning up his stator from HIGH voltage. Your problem so far seems to be LOW voltage. Your stator could already be partially shorted out, but you need to do the open circuit voltage test to see if it's putting out AC voltage at 5000 to 7000 RPM. The rectifier regulator is a two part device which has the six diodes that change AC from the stator into DC that the battery can use. The voltage regulating circuit is a silicon control rectifier that grounds out one phase of the stator when the voltage gets too high The silicon control rectifier is sometimes also called a "thyristor". When the SCR grounds one phase of the stator, that cuts the AC outout in half momentarily. The silicon control rectifier has enough built-in resistance, when it conducts electricity to ground it just gets hot without hurting itself. The remote sensing wire simply sends voltage to a component called a zener diode in the voltage regulating circuit of the rectifier regulator. A zener diode is a kind of diode that doesn't conduct electricity until the voltage reaches the desired level. Then th zener diode conducts electicity to the gate of the silicon contro rectifier, telling it to shunt the high voltage (around 15 to 16 volts) to ground. That's why the rectifier regulator is also called a "shunt type regulator". It just wastes excess voltage into the frame of the motorbike. - meantime, one of my electrician friends at work asked if I ha checked the coils yet. He said that it is possible if the resistance is too high on them they could be failing which would also impede th charging capacity of the bike's charging system. Have you ever heard anything like this before. It sure sound relevant due to how poorly the bike runs until it runs for a minute. It does not seem that it is an issue of warming up because even after it begins to run well it can go back at any moment to running poorly.- You might have loose connectors on the ignition control module or on the ignition coils themselves. If you want to see if you have enough voltage to produce adequate sparks, install a fully charged battery, remove the spark plugs and reinstall the plugs in the plastic connectors on the end of the ignition wires and crank the engine over while holding a spark plug about 1/4 of an inch away from the cylinder head. If you get a bright blue spark that jumps 1/4 of an inch, you have enough spark to rev up the engine to do your open circuit test. If you get a weak white spark that won't jump 1/4 of an inch, or it's orange or red, that's really weak and you'll need to figure out what the problem is. An electronic ignition system either works or it doesn't, the most likely problem for weak spark is dirty or loose connectors. If you don't have a weak spark, the most probable reason for bad running is dirty idle mixture jets. I've described what to do about that in this newsgroup about a bazillion times, so you can google that information up.[/QUOTE] Krusty, Well I just did the open circuit test and the readin never went over 1.0 volts with the multimeter set on 200vac. Also just received the Clymer manual and it said to test the resistanc between the white wire and black wire from the stator and upon testin them I got a reading of 1 ohm when the specs are between .4 and . ohms. Both results point to a bad stator but it still does not addres why the bike is moody. The smell of gas is overwhelming when the bike i 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 and then go back missing and backfiring.
