1981 GL1100
When I re-installed the engine, I must have rotated it so the CDI is out of phase.
I do know that the timing belts are set properly, that I have spark and that I have fuel. (I have already spent a week on this %^&^%)
My Clymer just doesn't give me any information.
I assume that i must remove the rear wheel to get to the CDI unit. Can I pull it, and rotate it without removing the engine.
Any suggestions as what to look for etc. Any help is appreciated. Thanks, lew

hi lew

the best manual for what you wish to know is the honda shop manaul. covers 80 though 83 goldwings. pricey--but worth it.

the shaft is a 2 peice a fair. one you can check with out pulling the back cover and one when you pull it. needless to say ,engine has to be out to check the every thing out right. just looked and there isn`t enough room between the swingarm cross peice and the engine . even with the rear tire and fender stuff removed.wayne.

I am really lost here. the Clymer says that the unit can only be installed one way. is it possible that the shaft is 180 out. because i have gas and spark, the only thing that it could be is the timing of the spark. Like I say I am at a loss. And---IU really don't want to pull that engine again if I don't have to. Thanks, lew

Lew, I don't see how the Pulse Generator could be assembled and locked into place 180 degrees out of phase. However here are two things I have seen happenthat caused the symptoms you are describing.

1) The dowel pin was left out during reassembly. This allows the Pulse Generator to spin aroundloose, you never know when or if it will fire.Dowel pin is about 1/8" diameter and 5/16" long. See pic.

2) The yellow and blue wires are reversed on the coils. This causes the coils to fire 180 degrees out. Try swapping these wires and see if it starts.

Thanks JackJon, I never removed the CPI unit from the back plate. Is it possible for that pin to fall out form the front of the back plate? Thanks, Lew

I somehow managed to do something similar to my 1100. When I tried to start it she simply backfired.

My solution was to swap over the feeds to the ignition colis and problem solved!

Hi Lew, the Honda manual shows the Pulse Generator being removed before the Engine Rear Cover can be removed.Using the terms in the picture, what was disassembled and what was left untouched.

Have you tried swapping the Blue and Yellow wires on the coils yet?

Ifyou have a timing light (induction style pick-up is easiest to use) your manual should show you how to check the ignition timing. (Not to be confused with the valve timing) Clip onto either plug wire 1 or 2 and the light should fire at the F1 mark, if you clip on plug wire 3 or 4 the light should fire at the F2 mark. Please understand that the ignition timing on the GW engine is not adjustable like an automobile engine. If the timing is off then something is amiss that will have to be found and corrected.

I am sorry this looks like the shotgun effect but until we separate the things that currently work from those that do not, it's all guessing.This problem is not insurmountable, and with your hands and eyes and the people on the forum helping, the problem will be solved and we will all learn something new.

Greetings Graham, i wsitched the coil wiare and it worked great for about two minutes. Then ran poorly then died. I swithced the wired back and it ran poorly for a couple of minutes.
Now I fear that the CPI unit is 'floating.' The big (very big) quesiton is can I slove the problem without pulling the engine. Thanks for the input, Lew
