would anybody be able to tell me what determines the firing order? I have 1 & 2 firing good but not 3 & 4 . not at idle.

I pulled the coils out and reversed them and put them back, that did no difference. with a volt meter on the wires from the pulse generator I got a small voltage reading from both sides. I believe it is good. and that leaves the ignition control module suspect. I will take it to the Honda dealer to get it checked, if for any reason they say it is good, then I will go through (everything) to remove the pulse generator. it takes time to do something right...

Dude, it just make sense that if the bike was running well before you removed the motor and is running poorly now, that the engine removal caused the problem. And since the problem seems to be that one coil is not getting a signal, that the wiring from the pulse generators is suspect.
It could have gotten pulled, or pinched, or the plug left of the coils could be failing, but I'll betcha a donut it's something in those PG wires.
It is late Sunday but I think you are right about that. I will dig into that next.

I don't want to blow a hole in your banana boat, but, I think you guys are confused as to how the PG's work, and why they can't be the problem.
The PG's send a signal to the control unit. The control pulses a ground to fire the coils. If it were just the coils being controlled, you might be on the right track. But, unfortunately, the control unit pulses ground for the fuel pump relay as well as the LCD on the Aspy's on the same circuit as the left coil.
If the fuel pump runs, and the LCD works correctly, the problem is neither the PG's nor the control unit.
Now I am really confused, what is an LCD? I get spark from both coils but only 1&2 works enough to run the engine. I do get spark on 3 & 4 but not to run the engine. that is why I asked about firing order. could something be out to cause 3 & 4 to not fire when it is supposed to?

You keep wanting to blame it on the ignition. A coil isn't going to fire poorly at idle, unless the coil fires poorly. Period.
I'm relatively certain you have a carb problem.
First check and make sure you didn't leave the vacuum hose disconnected on the #4 intake runner. I've done it. Pinch it with a pair of pliers, to verify no leaks.
If that doesn't help, remove the sync screw in the intake runner and give it a shot of carb cleaner. If the rpm's increase, you're too lean.]


what are you referring to as the intake runner and sync screw. in my book those terms don't exist.

I might say that you were on the right track. I was not the pgs or spark related. I removed the top of #3 carb and put a couple spoon fulls of gas in it while it was running. As soon as I did that, It reved up and ran good until the gas ran out. It gets fuel at the intake hose so I would say the carb is not getting fuel and needs overhauled which is my next job. thanks for all the input.

I pulled the carbs today and found that #s 3 and 4 carbs have the float pin clip was off during installation and is keeping the floats closed.( hence, no gas) I will put them back and make sure they work before I button it all up. I hope this is the (end) of a never ending saga.
